just use your calculator to find the angle with the given property. Then solve for x.
For example, tan 58.7° = 1.6443
Since the period of tan(x) is 180°, you have to find x where
90-2x = 58.7: 2x = 31.3, so x = 16
2x = 211, so x = 106
also, continuing on, x = 196,286
Do the others in like wise.
Given angle x,where 0 <= x <= 360 (degrees) solve for to the nearest degree.
a)cos(2x) = 0.6420
b)sin(x + 20) = 0.2045
c)tan(90 - 2x) = 1.6443
