16815.

Convert the following radian measure into degree measure1) 75°30' 2) 7π/12 radian3) (11π/18) radian

Answer»

${\huge{\green{ answer :}}}$

cosA=5/13

sinA=-√(1-cos^2A) (since theta is in 4TH QUADRANT)

i.e. sinA=-√144/169

=-12/13

tanB=-15/8

sinB=+(15)/√{(-15)^2+(8)^2} (B is in Q2)

i.e. sinB=15/17

cosB=tanB/sinB

i.e. cosB=-15/8 * 17/15

cosB=17/8

now

sin(A+B)=sinAcosB+cosAsinB

sin(A+B)=(-12/13)(17/8)+(5/13)(15/17)

={1/13}(-51/2 + 75/17)

=(1/13)(-710/34)

16821.	The mean and SD for a, b and 2 are 3 and2÷√3 respectively, The value of ab would be(a) 5 (b) 6(c) 11 (d) 3Please give Full Solution
Answer» ab = -5 Step-by-step explanation: The mean and STANDARD deviation for a b and 2 are 3 and 2 √ 3 respectively the VALUE of ab would be Mean = (a + b + 2)/3 = 3 => a + b + 2 = 9 => a + b = 7 Standard deviation = √∑(x - Mean)²/n => 2√3 = √∑(x - Mean)²/n squaring both sides => 12 = ∑(x - Mean)²/n n = 3 => 12 = ∑(x - Mean)²/3 => 36 = ∑(x - Mean)² ∑(x - Mean)² = (a-3)² + (b-3)² + (2-3)² = a² + 9 -6a + b² + 9 - 6b + 1 = a² + b² -6a -6b + 19 equating both a² + b² -6a -6b + 19 = 36 using a² + b² = (a + b)² - 2ab => (a+b)² - 2ab - 6(a+b) + 19 = 36 putting value of a + b = 7 => 7² - 2ab - 6(7) = 17 => 49 - 2ab - 42 = 17 => -2ab = 10 => ab = -5

16821.

The mean and SD for a, b and 2 are 3 and2÷√3 respectively, The value of ab would be(a) 5 (b) 6(c) 11 (d) 3Please give Full Solution

Answer»

ab = -5

Step-by-step explanation:

The mean and STANDARD deviation for a b and 2 are 3 and 2 √ 3 respectively the VALUE of ab would be

Mean = (a + b + 2)/3 = 3

=> a + b + 2 = 9

=> a + b = 7

Standard deviation = √∑(x - Mean)²/n

=> 2√3 = √∑(x - Mean)²/n

squaring both sides

=> 12 = ∑(x - Mean)²/n

n = 3

=> 12 = ∑(x - Mean)²/3

=> 36 = ∑(x - Mean)²

∑(x - Mean)² = (a-3)² + (b-3)² + (2-3)² = a² + 9 -6a + b² + 9 - 6b + 1

= a² + b² -6a -6b + 19

equating both

a² + b² -6a -6b + 19 = 36

using a² + b² = (a + b)² - 2ab

=> (a+b)² - 2ab - 6(a+b) + 19 = 36

putting value of a + b = 7

=> 7² - 2ab - 6(7) = 17

=> 49 - 2ab - 42 = 17

=> -2ab = 10

=> ab = -5

Prove with reason that in a parallelogram -(i) each diagonal divides it into congruent triangles;(ii) the lengths of opposite sides are equal and(iii) the opposite angles are equal in magnitude.

Answer»

ANSWER:

The opposite ANGLES of a PARALLELOGRAM are EQUAL (and conversely: if the opposite angles of a quadrilateral are equal, it is a parallelogram). The DIAGONALS of a parallelogram bisect each other (and conversely: if the diagonals of a quadrilateral bisect each other, it is a parallelogram).

16845.	(1-sin theta+cos theta) square prove that 2 (1+cos theta)(1-sin theta)
Answer» To prove: $(1-sin\,\theta+cos\,\theta)^2=2(1+cos\,\theta)(1-sin\,\theta)$ CONSIDER, LHS = $(1-sin\,\theta+cos\,\theta)^2$ USING ( a + B )² = a² + b² + 2ab, we get = $(1-sin\,\theta)^2+cos^2\,\theta+2\times cos\,\theta\times(1-sin\,\theta)$ Again using ( a - b )² = a² + b² - 2ab, we get $= 1+sin^2\,\theta-2\times sin\,\theta+cos^2\,\theta+2cos\,\theta-2cos\,\theta\:sin\,\theta$ $= 1+sin^2\,\theta+cos^2\,\theta-2\times sin\,\theta+2cos\,\theta-2cos\,\theta\:sin\,\theta$ $= 1+1-2\times sin\,\theta+2cos\,\theta-2cos\,\theta\:sin\,\theta$ $= 2-2\times sin\,\theta+2cos\,\theta-2cos\,\theta\:sin\,\theta$ $= 2(1-sin\,\theta)+2cos\,\theta(1-sin\,\theta)$ $= (1-sin\,\theta)(2+2cos\,\theta)$ $= 2(1-sin\,\theta)$ = RHS Hence The relation is proved !!!!!!

(1-sin theta+cos theta) square prove that 2 (1+cos theta)(1-sin theta)

Answer»

To prove: $(1-sin\,\theta+cos\,\theta)^2=2(1+cos\,\theta)(1-sin\,\theta)$

CONSIDER,

LHS = $(1-sin\,\theta+cos\,\theta)^2$

USING ( a + B )² = a² + b² + 2ab,

we get

= $(1-sin\,\theta)^2+cos^2\,\theta+2\times cos\,\theta\times(1-sin\,\theta)$

Again using ( a - b )² = a² + b² - 2ab,

we get

$= 1+sin^2\,\theta-2\times sin\,\theta+cos^2\,\theta+2cos\,\theta-2cos\,\theta\:sin\,\theta$

$= 1+sin^2\,\theta+cos^2\,\theta-2\times sin\,\theta+2cos\,\theta-2cos\,\theta\:sin\,\theta$

$= 1+1-2\times sin\,\theta+2cos\,\theta-2cos\,\theta\:sin\,\theta$

$= 2-2\times sin\,\theta+2cos\,\theta-2cos\,\theta\:sin\,\theta$

$= 2(1-sin\,\theta)+2cos\,\theta(1-sin\,\theta)$

$= (1-sin\,\theta)(2+2cos\,\theta)$

$= 2(1-sin\,\theta)$

= RHS

Hence The relation is proved !!!!!!
