2.	The complementry angle are suvh that one is 1/3rd of the other find the measure of each angle
Answer» Answer: Step-by-step explanation: Answer: 54° Step-by-step explanation: Complementary angles add up to 90 degrees. Assign variable for the angles. Angle one = x Other angle = y We KNOW that the TWO angles are equal each other. Set up equations that represents this. x + y = 90 defines the total angles. 2x = 3y --> 2x - 3y = 0 defines the equality of the angles. We have a system of equations. x + y = 90 eq1 2x - 3y = 0 eq2 Substitute eq1 into eq2. We can get eq2 in terms of x. 2x - 3(90 - x) = 0 Solve for x. 2x - 270 + 3x = 0 5x - 270 = 0 5x = 270 x = 54 Substitute this value of x into eq1 to solve for y. y = 90 - x y = 90 - 54 y = 36 The angles are 36 and 54. The LARGER angle is 54 degrees. Hope it HELPS you.

The complementry angle are suvh that one is 1/3rd of the other find the measure of each angle

Answer»

Answer:

Step-by-step explanation:

Answer: 54°

Step-by-step explanation:

Complementary angles add up to 90 degrees. Assign variable for the angles.

Angle one = x

Other angle = y

We KNOW that the TWO angles are equal each other. Set up equations that represents this.

x + y = 90 defines the total angles.

2x = 3y --> 2x - 3y = 0 defines the equality of the angles.

We have a system of equations.

x + y = 90 eq1

2x - 3y = 0 eq2

Substitute eq1 into eq2. We can get eq2 in terms of x.

2x - 3(90 - x) = 0

Solve for x.

2x - 270 + 3x = 0

5x - 270 = 0

5x = 270

x = 54

Substitute this value of x into eq1 to solve for y.

y = 90 - x

y = 90 - 54

y = 36

The angles are 36 and 54.

The LARGER angle is 54 degrees.

Hope it HELPS you.

6.	2/9,7/12,13/20,1/4 incriminating order
Answer» Answer: HIGHEST to lowest 13/20, 7/12, 1/4, 2/9 or lowest to highest 2/9,1/4,7/12,13/20 Step-by-step explanation: first we make their denominators equal by finding the common multiple amoungst them which is 180 as it can be divided by 20, 12, 4, 9, which are the denominators. so, 180/20=9 therefore 13/209/9=117/180 180/12=15 therefore7/1215/15=105/180 180/4=45 therefore1/445/45=45/180 180/9=20 therefore2/920/20=40/180 In DESCENDING order it is 117/180,105/180,45/180.40/180 which is same as 13/20,7/12,1/4,2/9 But 2/9,1/4,7/12,13/20 in ASCENDING order

2/9,7/12,13/20,1/4 incriminating order

Answer»

Answer:

HIGHEST to lowest

13/20, 7/12, 1/4, 2/9 or

lowest to highest

2/9,1/4,7/12,13/20

Step-by-step explanation:

first we make their denominators equal by finding the common multiple amoungst them which is 180 as it can be divided by 20, 12, 4, 9, which are the denominators.

so, 180/20=9

therefore 13/20*9/9=117/180

180/12=15

therefore7/12*15/15=105/180

180/4=45

therefore1/4*45/45=45/180

180/9=20

therefore2/9*20/20=40/180

In DESCENDING order it is 117/180,105/180,45/180.40/180

which is same as 13/20,7/12,1/4,2/9

But 2/9,1/4,7/12,13/20 in ASCENDING order

Please solve this word problem. 11. Find the length of the diagonal of a rectanglewhose sides are 15 cm and 8 cm.

Answer»

$\Large{\underline{\underline{\mathfrak{\bf{Question}}}}}$

Find the LENGTH of the diagonal of a RECTANGLE whose sides are 15 cm and 8 cm.

$\Large{\underline{\underline{\mathfrak{\bf{Solution}}}}}$

$\Large{\underline{\mathfrak{\bf{\red{Given}}}}}$

Length of rectangle = 15 cm
width of rectangle = 8 cm

$\Large{\underline{\mathfrak{\bf{\red{Find}}}}}$

Length of diagonal

$\Large{\underline{\underline{\mathfrak{\bf{Explanation}}}}}$

In Rectangle ABCD ,

CD is diagonal of this rectangle ,

Here,

AB = 8 cm = CD
BC = 15 cm = DA

we know,

$\small\boxed{\boxed{\sf{\red{\:Length_{diagonal}\:=\:\pm\sqrt{(lenght)^2+(width)^2}}}}}$

Keep value of Length and width ,

$\mapsto\sf{\:Length_{diagonal}\:=\:\pm\sqrt{(15)^2+(8)^2}} \\ \\ \\ \mapsto\sf{\:Length_{diagonal}\:=\:\pm\sqrt{225+64}} \\ \\ \\ \mapsto\sf{\:Length_{diagonal}\:=\:\pm\sqrt{289}} \\ \\ \\ \mapsto\sf{\:Length_{diagonal}\:=\:\pm\:17}$

But, we know, length always be positive .

So, neglect negative (-ve)sign ,

And, Take positive (+ve) sign .

$\mapsto\sf{\orange{\:Length_{diagonal}\:=\:\:17\:cm}}$

$\Large{\underline{\mathfrak{\bf{\green{Hence}}}}}$

Length of diagonal of rectangle = 17 cm

So, the MULTIPLICATIVE inverse of a number is a number that NULLIFIES the impact of the number to identity 1. THUS the multiplicative inverse of a number is a number by which the multiplication results in 1. ... Similarly, the multiplicative inverse of -17/7 is 7/-17. Another WORD for multiplicative inverse is 'reciprocal.

⠀⠀ıllıllı uoᴉʇnloS ıllıllı

$\setlength{\unitlength}{1.0 cm}}\begin{picture}(12,4)\thicklines\put(1,1){\line(1,0){6.5}}\put(1,1.1){\line(1,0){6.5}}\end{picture}$

In ∆BOC and ∆AOD, We have:

∠BOC = ∠AOD

BC = AD [Given]

∠BOC = ∠AOD [Vertically opposite angles]

∴ ∆OBC ≅ ∆OAD [By AAS CONGRUENCY]

➠ OB = OA [By C.P.C.T.]

i.e., O is the mid-point of AB.

Thus, CD bisects AB.

Answer»

Question: 1). 4(n - 2) = 24

Solution: 4(n - 2) = 24

=> 4n - 8 = 24

=> 4n = 24 + 8

=> 4n = 32

=> n = 32/4

=> n = 8

_____________________

Question: 2). 0 = 16 + 4(m - 6)

Solution: 0 = 16 + 4(m - 6)

=> 4m = 8

=> m = 8/4

=> m = 2

=> 10x - 4x = 16 + 15

=> 6x = 31

What is the are of a parallelogram whose base is 7cm, is 5cm

Answer»

It seems minor mistake in the question ;

Correct Question :

What is the AREA of a parallelogram whose base is 7cm, and its height is 5cm.

Given :

Base of the parallelogram = 7 cm.

Height of the parallelogram = 5 cm

To find :

Area of Parallelogram = ?

Step-by-step explanation:

We know that,

Area of Parallelogram = Base × Height

Substituting the values in the above formula, we get,

= 7 × 5

= 35.

Therefore, The Area of the parallelogram = 35 cm².

BRAINLY Extra knowledge :

Area of Parallelogram = Base × Height

Perimeter of Parallelogram = 2(a+b)

PROPERTIES of Parallelogram :

Opposite sides are congruent, AB = DC

Opposite angles are congruent D = B

If one angle is RIGHT, then all angles are right.

The diagonals of a parallelogram bisect each other.

The complementry angle are suvh that one is 1/3rd of the other find the measure of each angle​

Answer: 54°

Step-by-step explanation:

Complementary angles add up to 90 degrees. Assign variable for the angles.

Angle one = x

Other angle = y

We KNOW that the TWO angles are equal each other. Set up equations that represents this.

x + y = 90 defines the total angles.

2x = 3y --> 2x - 3y = 0 defines the equality of the angles.

We have a system of equations.

x + y = 90 eq1

2x - 3y = 0 eq2

Substitute eq1 into eq2. We can get eq2 in terms of x.

2x - 3(90 - x) = 0

Solve for x.

2x - 270 + 3x = 0

5x - 270 = 0

5x = 270

x = 54

Substitute this value of x into eq1 to solve for y.

y = 90 - x

y = 90 - 54

y = 36

The angles are 36 and 54.

The LARGER angle is 54 degrees.
