Question

The measures of two supplementary angles total 180 degrees. The measure of angle y is 65 degrees less than the measure of angle x. What are the measures of the angles?
The measure of angle x is 122.5 degrees. The measure of angle y is 57.5 degrees.
The measure of angle x is 115 degrees. The measure of angle y is 65 degrees.
The measure of angle x is 57.5 degrees. The measure of angle y is 122.5 degrees.
The measure of angle x is 65 degrees. The measure of angle y is 115 degrees.

Answer 1

answer is c because 57.5 +122.5=180 and 57.5+65=122.5

Answer 2

y=x-65
x+y=180
=x+x-65=180
=2x=180+65
=x=225/2
=x=112.5
y=180-112.5
=y=67.5
