The Sin ∠x = .5299. What is the measure of ∠x ? ∠ x =

Answer 1

You would use the inverse trigonometric function sin^-1(x).

sin(x) = 0.5299

sin^-1(sin(x)) = sin^-1(0.5299)

x = 32.00 degrees

Since sin^-1(x) is the inverse function of sin(x), we could say that sin^-1(sin(x)) = x by the definition of function inverse.
