Expert Answer:
In triangle ABC,
A and B are acute angles hence C is right angle.
A + B = 90
B = 90 - A
Sin2 A + sin2 B
= sin2 A + sin2 (90 - A)
= sin2 A + cos2 A
= 1

- tanA =cotB find A+B=?
- If cos(90 - A ) = 0 then sin( A + B ) =
- SHOW THAT cos 38°cos 52°- sin 38°sin 52° =0
- if cos (40°-X)=30sin find the value of X
- evaluate cot (90-theta) -tan theta
- Evaluate cos48°cos42°–sin48°sin42°
- Evaluate cot 12 cot 38 cot 52 cot 60 cot 78
- If tan 7theta=cot(5theta–30degree),both angles are acute angles,find the value of theta
- ySin²63°+ySin²27°/4cos²17°+4cos²73°=-½
