Question

A.If 0 is less than or equal to thita is less than 360 ,find all possible value of thita such that :
1.Sin thita =0.5623

Answer 1

theta, not thita. I'll just use x. You want

sin x = 0.5623
Since sin is positive in QI and QII, and sin(34.2°) = 0.5623

the solutions are

x = 34.2° and 180-34.2°

Answer 2
