Find 0⁰ less than A less than 180⁰ if sinA = 1/2

Since the angle A is greater than 0 degrees and less than 180 degrees, that is, it belongs to the first or second quarter. The sine values in the first quarter take positive values, and the sine values in the second quarter take negative values. Then sin A = 1/2 belongs to the first quarter, that is, the angle A = 60 degrees.

Answer: 60 degrees.
