Solve for x then find the measure of the angle given
ololo11 [35]

Answer:

∠ MPQ = 125°

Step-by-step explanation:

∠ LMN and ∠ MPQ are corresponding angles and are congruent , so

5x = 3x + 50 ( subtract 3x from both sides )

2x = 50 ( divide both sides by 2 )

x = 25

Then

∠ MPQ = 3x + 50 = 3(25) + 50 = 75 + 50 = 125°
