To find the measure of ∠QRS, we can use the fact that the sum of two supplementary angles is equal to 180 degrees.
So, x+40 + x = 180
2x + 40 = 180
Subtracting 40 from both sides:
2x = 140
Dividing both sides by 2:
x = 70
Therefore, the measure of ∠QRS is x+40 = 70+40 = 110 degrees.
Two angles are supplementary and have measures m∠QRS=(x+40)° and m∠SRT=x° . What is the measure of ∠QRS ?(1 point)
