The degree measures of two angles on a line are expressed as 2x+50 and 4X-20. What is the measure of the larger angle?

Two complementary angles are represented by expressions 3x+5 and 2x+10. Find the measures of both angles . If two angles are complementary, then the sum is 90 degrees so we have: (3x+5) + (2x+10) = 90 5x+15 = 90 5x = 75 x = 15. measure of one angle then is: 3x+5 = 3(15)+5 = 45+5 = 50 degrees. measure of second angle then is:
