Question

if cos²0=0.64, what is the value of 1)sin²0.2)sin0 (0 is theta) write full answer
​

Answer 1

Answer:

1) 0.36  2) 0.6

Step-by-step explanation:

given that cos²θ = 64

1) sin²θ = 1 - cos²θ

            = 1 - 0.64

            = 0.36

2) sinθ = √sin²θ

           = √0.36

           = √(0.6)²

           = 0.6
