Question

Need help for 56 it says solve equation to the nearest tenth use the given restrictions

Answer 1

Problem N 56

we have

sin∅=0.8 ----------> interval [-90,90] ----> that means the angle lie in the I or IV quadrant

∅=sin^-1(0.8)

∅=53.1 degrees

In the IV quadrant, the value of sine is negative (so in the IV quadrant there is no solution)

The answer is

∅=53.1 degrees
