Two angles are supplementary and have measures mLQ RS = (2 + 40) ° and m LSRT = x°. What is the measure of LQ RS? (1 point)
• 701
• 25°
• 110°
• 180°
The sum of two supplementary angles is 180°.
Given that mLQ RS = (2 + 40)° = 42° and m LSRT = x°, we can set up the equation:
mLQ RS + m LSRT = 180°
42° + x° = 180°
x° = 180° - 42°
x° = 138°
Therefore, the measure of LQ RS is 138°.
Answer: None of the above
