Given that sin 0 = 21/29, what is the value of cose, for 0° <0<90°? please help

3rd option

Step-by-step explanation:

Using the identity

sin²x + cos²x = 1  ( subtract sin²x from both sides )

cos²x = 1 - sin²x ( take the square root of both sides )

cosx = ±

Given

sinθ = and 0 < θ < 90 , then

cosθ

=
