Two angles are supplementary and have measures m∠QRS=(x+40)° and m∠SRT=x° . What is the measure of ∠QRS ?(1 point) Responses 25° 25 degrees 70° 70 degrees 180° 180 degrees 110°
Since two angles are supplementary, their measures add up to 180°.
Therefore, (x+40) + x = 180°
2x + 40 = 180°
2x = 140°
x = 70°
Therefore, the measure of angle QRS is (70 + 40) = 110°. Answer: \boxed{110°}.
