Since the two angles are supplementary, their measures add up to 180 degrees.
Therefore, we have the equation:
(x + 40) + x = 180
Combining like terms, we get:
2x + 40 = 180
Subtracting 40 from both sides, we get:
2x = 140
Dividing both sides by 2, we get:
x = 70
Therefore, the measure of QRS is x + 40 = 70 + 40 = 110.
The correct answer is A. 110.
Two angles are supplementary and have measures m QRS = (x + 40) and m SRT = x. What is the measure of QRS?
