In this figure, m∠1 = (15x−5)° and m∠2 = (10x+35)°. What is m∠1?

Question

A. 31°

B. 65°

C. 85°

D. 115°

Answer 1

There is no diagram, so we have NO way of knowing how those angles are related...

But then you say the answer is 115, so apparently, the angles are equal

15x - 5 = 10x + 35

5x - 5 = 35

5x = 40

x=8

then angle #1 is 15(8)-5 = 120-5 = 115

and angle #2 is 10(8) +35 = 80+35 = 115

so the angles are bisected or vertical
