Two angles are complementary. The first angle is 2x degrees. The second angle is (3x +5) degrees. Determine the measure of each

bixtya [17]

Answer:

70 and 110

Step-by-step explanation:

First angle -- 2x

Second angle -- 3x + 5

Therefore,

2x + 3x + 5 = 180

5x = 175

x = 35

Therefore, 2x -- 70

3x + 5 -------------110
