Answer 7

What does it mean for two angles to be supplementary?

They add to 180 degrees.

Answer 8

m<7 = 2*m<2

Let m<2 = x

Then, m<7 = 2x

The two angles are supplementary.

Answer 9

x + 2x = 180 --> Solve for x and post what you get, okay? @kessj

Answer 10

im sorry but 60

Answer 11

@Directrix

Answer 12

Okay, x = 60. That is the m<2

The m<7 = 2* 60 = ? @kessj

Answer 13

Two times 60 equals ? @kessj
