Question

The value of sin² 29° + sin² 61° is
A. 1
B. 0
C. 2 sin² 29°
D. 2 cos² 61

Answer 1

Answer:

its nearly 1.1..........

so answer is A

Answer 2

A. 1

Step-by-step explanation:

sin² 29° + sin² 61° = sin² 29° + cos²(90-61°)  

= sin² 29° + cos² 29° = 1

based on identities:

sin (90 - θ) = cosθ

sin²θ + cos²θ = 1

Option A is the answer.
