Question

The ratio of the measures of two supplementary angles is 7:3. Find the measures of the angles.

Answer 1

If "The ratio of the measures of two supplementary angles is 7:3", then

7x+3x = 180

Solve for x. Then use this to find 7x and 3x

Answer 2

7+3 = 10, so the angle, which equals 180, is in 10 parts.
180/10 = 18.
So the angles are then 18*7 and 18*3

Answer 3

A. 126° and 54°
B. 72° and 18°
C. 159° and 21°
D. 69° and 21°

Answer 4

18*7 = 126
18*3 = 54
So then A...
