An angle in standard position such that sinÈ = 5/13. Determine the possible values of È, to the nearest degree.

Answer: I got 23°. (How do I get the second one?)

SinTheta=sin(180-Theta)
The sine curve is symmetrical about 90 degrees.
So sin(x) has the same value as sin(180-x).

Review of the unit circle will certainly help as well.
