Two angles are complementary. The first angle is 2x degrees. The second angle is (x+30) degrees. Determine the larger angle.
Answer provided by our tutors
Since the two angles are complementary this means that 2x and (x+30) add up to 90:
2x + (x + 30) = 90

x = 20 degrees
2*20 = 40
20 + 30 = 50
The larger angle is 50 degrees.
