Find the value of θ between 0° and 360° satisfying the equation 5 sin θ = 4
θ= sin-1(4/5)
= 53.13, 143.13
θ= sin-1(4/5)
= 53.13, 143.13

sinØ = 4/5 = .8
Your first angle is correct, so the angle in quad II should be 180-53.13 = 126.87°
check with a calculator, also check your second answer to see that it is incorrect.
