Question

if tan theta is equal to 1 by root 3 find the value of sin into 90 degree minus theta​

Answer 1

Answer :-

Value of sin (90 - θ)° is 1/√3

Explanation :-

Finding the value of θ

tan θ = 1/√3

Also, tan 30° = 1/√3

From the above 2 equations

tan θ = tan 30°

Comparing on both sides

θ = 30°

Finding the value sin (90 - θ)°

sin (90 - θ)°

= sin (90 - 30)°

[ ∵ θ = 30°]

= sin 60°

= 1/√3

[ ∵ sin 60° = 1/√3]

∴ the value of sin (90 - θ)° is 1/√3
