Answer:

x= 9.04°

7x = 63.28°

8x = 72.32

44.4° + 63.28° + 72.32° = 180°

Explanation:

The sum of supplementary angles is 180°

Set up an equation with the given information, then solve for x.

44.4 + 7x + 8x = 180

7x +8x = 180-44.4

15x = 135.6 Divide both sides by 15

x = 9.04

Substitute for x and multiply by 7, then 8 to find the measures of the unknown angles.
