The answer given on the calculator for arcsin .9565 is 73.10. In the above example, the only measurement that was required was the measure of. Therefore, two solutions for the angle had no bearing on the rest of the triangle. However, if we were solving the triangle, two solutions would have a direct impact on the triangle.
