What will be an ideal response?
Refer to the figure and use the given information to solve the triangle. Round angles to the nearest degree and side lengths to one decimal place.
b = 7.5, c = 14.9
A. A = 30, B = 60, C = 90, a = 12.6, b = 7.5, c = 14.9 B. A = 60, B = 30, C = 90, a = 11.4, b = 7.5, c = 14.9 C. A = 45, B = 45, C = 90, a = 13.2, b = 7.5, c = 14.9 D. A = 60, B = 30, C = 90, a = 12.9, b = 7.5, c = 14.9
