Two angles are supplementary have measures M angle QRS equals X +40 and M angle SRT equals X what is the measure of angle QRS

1 answer

Since two angles are supplementary, their measures add up to 180 degrees.

Let's denote the measure of angle QRS as y.

According to the given information, the measure of angle SRT is x, and the measure of angle QRS is x + 40.

Since the sum of the measures of the two angles is 180 degrees, we can set up the equation:

x + (x + 40) = 180

By combining like terms:

2x + 40 = 180

By subtracting 40 from both sides:

2x = 140

By dividing both sides by 2:

x = 70

Substituting the value of x into the expression for the measure of angle QRS:

y = x + 40 = 70 + 40 = 110

Therefore, the measure of angle QRS is 110 degrees.
