Two angles that are supplementary have a ratio of 7 to 5. what are their measures?

Supplementary angles are two angles whose measures add to 180 degrees.
7 + 5 = 12, so the angles cannot possibly measure 7 deg and 5 deg, but their measures are in a 7 to 5 ratio.
If we multiply both 7 and 5 by the correct number, we will get the measures of the two angles that are supplementary and in a 7 to 5 ratio.
Let the number be x.

7x and 5x are also in a 7 to 5 ratio.

7x and 5x are the measures of two supplementary angles, so their sum is 180.

7x + 5x = 180

12x = 180

x = 15

The number we were looking for is 15.

7x = 7(15) = 105
5x = 5(15) = 75

The angles measure 105 deg and 75 deg.

For the first question the answer is a, for the second c, for the third d, for the 4th b, for the 5th a

C, e, and a (hope it )
