Answer 1

<2 = 45

< 7 = 135

< 3 = 135

< 5 = 135

<8 = 45

< 6 = 45

Explanation:

Angles 2 and 7 are supplemental angles. This means that together they add to 180.

x + 3x = 180 Combine like terms

4x = 180 Divide both sides by 4

x = 45

<2 = 45

Angle 7

3x Substitute 45 for x

3(45)

135

Angle 3

Corresponding angle to 7. Corresponding angles are congruent (equal).

Angle 5

Vertical to angle 7. Vertical angles are congruent.

Angle 8

Alternate exterior angle to 7. Alternate exterior angels are congruent.

Angle 6
