Question

Find all solutions to the equation.

sin x = square root of three divided by two.

Answer 1

x = 60°

Explanation:

Special Angles :

sin = opposite divided by hypotenuse

opposite of angle 60° is square root of three

hypotenuse is two

Answer 2

x=60+k.360 or x =120+k.360

Explanation:

1. 
   `sin x = ( √(3) )/(2 \\ ?)`
2. 
   `ref \: angle = 60 \\ x = 120+ k.360 \\ x = 60 + k360`
