Question

If cos theta is equal to half sin x is equal to half then find the value of theta + x

Answer 1

Answer:

150°

Step-by-step explanation:

cos θ = 1/2 sin x = 1/2

Here cos θ = 1/2

Hence cos θ = cos 60°

= > θ  = 60°

1/2 sin x = cos θ

= > 1/2 sin x = cos 60

= > 1/2 sin x = 1/2

= > sin x = 1

= > sin x = sin 90°

x = 90°

θ + x

= > 90° + 60°

= > 150°

Answer 2

Answer:

150°


Step-by-step explanation:


cos θ = 1/2 sin x = 1/2


Here cos θ = 1/2


Hence cos θ = cos 60°

= > θ  = 60°


1/2 sin x = cos θ

= > 1/2 sin x = cos 60

= > 1/2 sin x = 1/2

= > sin x = 1

= > sin x = sin 90°


x = 90°

θ + x

= > 90° + 60°

= > 150°
