Solve.
Two angles are complementary if their sum is 90. If the measure of the first angle is x, and the measure of the second angle is (3x - 2), find the measure of each angle.

1st angle = 22; 2nd angle = 64
1st angle = 23; 2nd angle = 67
1st angle = 31; 2nd angle = 59
1st angle = 22; 2nd angle = 68
