Question

can anyone tell me the answer

Answer 1

Hey friend,

• sun + sun + sun = 33

3 sun = 33

sun = 33/3

sun = 11

• sun + cloud + sun = 25

11 + cloud + 11 = 25

cloud = 25 - 22

cloud = 3

• Cloud + cloud + moon = 11

3 + 3 + moon = 11

moon = 11 - 6

moon = 5

• 2cloud + moon × 2sun = (to be calculated)

2(3) + 5 × 2(11)

= 6 + 5 × 22

= 6 + 110

= 116

Hope this helps!!!

Answer 2

Answer:

Step-by-step explanation: Given: xCostheta minus ySintheta=A,xSinthetaplusyCostheta=b .

To prove : that xsquare plus ysquare=asquare plus bsquare

Proof :Applying (a +b)2 ;

X2 cos2 that a +y2sin2 theta - 2xy costheta sintheta + x2sin2theta + y2cos2+2xy sintheta costheta

Cancelling +2xy...... and - 2xy.....

We get :

X2cos2theta +y2sin2theta + x2sin2theta+y2cos2theta

Taking x2and y2as common on one side and cos2theta and sin2theta as common on othe side, we get ;

X2+y2=cos2theta + sin2theta

Where a and b are cos2theta and sin2theta repectively.

Therefore : x2+y2= a2+b2.
