Find the value of X please answer this it's urgent

Answer»

ANSWER:

Angle DOB = Angle DOC + Angle COB

90° = Angle DOC + 70°

Angle DOC = 90° - 70°

Angle DOC = 20°

Angle DOC + Angle DOE = Angle EOC

20° + x = 90°

x = 90° - 20°

Factorise:pq²+q(p-1) -1=?

Answer»

Solution

➟ pq² + q(p - 1) - 1

➟ pq² + qp - q - 1

➟ pq(q + 1) - 1(q + 1)

➟ (q + 1)(pq - 1)

Some IDENTITIES

(a + B)² = a² + b² + 2ab
(a - b)² = a² + b² - 2ab
a² - b² = (a + b)(a - b)
(a + b)³ = a³ + b³ + 3AB(a + b)
(a - b)³ = a³ - b³ - 3ab(a - b)

2. By selling a T. v. for rupee 8000 a shopkeeperloses 20 percent of his cost. if he sells it for rupee 11000, what profit or loss wouldbe there for him.

Answer»

$\large\bf\underline{Given:-}$

SELLING price = RS. 8000
Loss = 20% of his cost

$\large\bf\underline {To \: find:-}$

if he sells it for rupee 11000, what profit or loss would be there for him.

$\huge\bf\underline{Solution:-}$

Selling price of T.V = 8000
Loss% = 20 %

$\large \star \tt \: C.P = \frac{100 \times \: S.P. }{100 - loss\%} \\$

$\dashrightarrow \tt \: C.P = \frac{100 \times 8000}{100 - 20} \\ \\ \dashrightarrow \tt \: C.P = \cancel \dfrac{800000}{80} \\ \\ \dashrightarrow \bf \: C.P = 10000$

According to question:-

if he sells it for rupee 11000 then,

S.P = 11000
C.P = 10000

Here,

C.P < S.P = profit

$\large \star \bf \: Profit = selling \: price - cost \: price$

≫Profit = 10000 - 11000

≫ Profit = Rs. 1000

he is having a profit of RS .1000 if he sells the T.V for Rupee 11000.

$\large \star \bf \: Profit\% = \frac{Profit}{C.P}\times{100}$

Profit% = (1000/10000)× 100

Profit% = 10%

$\rule{200}3$

$\boxed{ \begin{minipage}{9cm}\large \boxed{ \bf \:when S.P.\:is \:greater \:then \:C.P}\\ \\ \bf\:Profit =S.P - C.P \\Profit\% = (Profit) \times 100\\ \bf \: S.P = C.P + Gain\\C.P = S.P - Gain \\ \\To \: find \: S.P\: when \: C.P \: and \: profit \%\: are \: given : - \\ \\S.P = \frac{(100 + profit\%) \times \: C.P }{100} \\ \\ To \: find \:C.P \: when \: S.P\: and \: profit\% \: are \: given : - \\ \\ C.P = \frac{(100 \times \: S.P) }{100 + profit\%} \\ \end{minipage}}$

Answer»

$\huge\bigstar\underline\mathcal\blue{Answer:-}$

Solution:

CONSIDER the given triangle as ABC as shown in the FIGURE above.

Here, L B =90° ______( RIGHT angle of a triangle)

L C= 53° ________(given )

Now, According to the sum of angles of triangle property,

The sum of all angles of a triangle is 180°.

Thus,

L A + L B + L C =180°

L A + 90 + 53 =180°

L A + 143 =180°

Now,

L A = 180 - 143

L A = 32°

46.	Find the quadrilateral ABC, shown in the figure is a parallelogram. find the measure of x,y and z
Answer» Answer: Angle ABC = ?? Angle B = 44° Therefore, Angle B = 180° - 44° = 136° Angle B congruent to angle D ...... Since opposite ANGLES of a PARALLELOGRAM are congruent Therefore Angle B = angle D = 136° Angle A = angle B (exterior angle B) Since an exterior angle is SIMILAR to an interior angle lying on an equal ray Therefore Angle A = 44° Angle C = angle A Since opposite angles of a parallelogram are congruent Therefore, Angle A = angle C = 44° Final Answer :- x = angle C /2 = 44/2 = 22° y = angle D = 136° z = angle A /2 = 44/2 = 22° Answer :- x = 22° , y = 136° , z = 22°

46.

Find the quadrilateral ABC, shown in the figure is a parallelogram. find the measure of x,y and z

Answer»

Answer:

Angle ABC = ??

Angle B = 44°

Therefore, Angle B = 180° - 44°

= 136°

Angle B congruent to angle D ......

Since opposite ANGLES of a PARALLELOGRAM are congruent

Therefore Angle B = angle D = 136°

Angle A = angle B (exterior angle B)

Since an exterior angle is SIMILAR to an interior angle lying on an equal ray

Therefore Angle A = 44°

Angle C = angle A

Since opposite angles of a parallelogram are congruent

Therefore, Angle A = angle C = 44°

Final Answer :- x = angle C /2 = 44/2 = 22°

y = angle D = 136°

z = angle A /2 = 44/2 = 22°

Answer :- x = 22° , y = 136° , z = 22°

Answer» Answer: Total distance = 104 km AVERAGE speed = 20.8 km/hr Step-by-step explanation: GIVEN : Object MOVES with a speed of 16 km/hr for two hours Object moves with a speed of 24 km/h for next three hours To find : Average speed Total distance TRAVELLED by the car Distance = speed×time Distance travelled in the first interval = 16×2 Distance travelled in the first interval = 32 km Distance travelled in the second interval = 24×3 Distance travelled in the second interval = 72 km Total distance distance = 72+32 = 104 km The total distance covered by the car is equal to 104 km Average speed = total distance / total time Total time = 2+3 = 5 hours Average speed = 104/5 Average speed = 20.8 km/hr The average speed of the car is equal to 20.8 km/hr

An object moves with a speed of 16 km/h for two hours and with the speed of 24 km/h for the next three hours . Find the average speed of the object and the total distance moved . ANSWER MY QUESTION..I'LL MARK U AS BRAINLIEST

Answer»

Answer:

Total distance = 104 km

AVERAGE speed = 20.8 km/hr

Step-by-step explanation:

GIVEN :

Object MOVES with a speed of 16 km/hr for two hours

Object moves with a speed of 24 km/h for next three hours

To find :

Average speed

Total distance TRAVELLED by the car

Distance = speed×time

Distance travelled in the first interval = 16×2

Distance travelled in the first interval = 32 km

Distance travelled in the second interval = 24×3

Distance travelled in the second interval = 72 km

Total distance distance = 72+32 = 104 km

The total distance covered by the car is equal to 104 km

Average speed = total distance / total time

Total time = 2+3 = 5 hours

Average speed = 104/5

Average speed = 20.8 km/hr

The average speed of the car is equal to 20.8 km/hr
