Question

Sinθ = 3/5 the value of (1 - cos²θ) :

Answer 1

use the trigonometric identity

it is the correct answer

Answer 2

Answer:

9/25

Step-by-step explanation:

sin theta = 3/5

H² = B²+P²

(5)²= (3)²+B²

25=9+B²

25-9 = B²

16 = B²

√16 = B

4 = B

1 - cos²theta = B/H

1 - (4/5)²

1 - 16/25

9/25

I hope it will easy to solve
