You will get something like sin(an angle)= a number from the figure, and then you take the inverse of it.

Example:

\(\tan x = \dfrac{3}{2}\\ x = \tan^{-1}\dfrac{3}{2}\approx56.3^{\circ}\)Last step is done by calculator.

Even this one!!:

\(\sin x =\dfrac{1-\sqrt5}{2}\\ x = \sin^{-1}\dfrac{1-\sqrt5}{2}\approx 321.8^{\circ}\)
