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

Answer 1

Hint:

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

10x=180

Answer 3

simplify

Answer 4

i'm so confused !

Answer 5

What is 180 divided by 10

Answer 6

18

Answer 7

So x = 18

Answer 8

Now use this to find 7x and 3x

Answer 9

Right so plug in 18 as x

Answer 10

I'll do 7x

7x = 7*18

7x = 126

Answer 11

7*18 and 3*18=180

Answer 12

3*18 = 54, not 180
