The adjacent angles are proportional to the numbers 6 and 9. Find these angles.

The sum of adjacent angles is 180 degrees. Let be
6 + 9 h = 180 g
15 h = 180 g
180/15 = 12 degrees – 1 part of the angle
12 * 6 = 72 degrees – an angle that is proportional to 6
12 * 9 = 108 degrees – an angle that is proportional to 9
Answer: 72 and 108
