A.)
If ∠3 = 5x - 1, and ∠5 = 3x + 11, then x =
<3 = <5
 5x - 1 = 3x + 11
2x = 12
x = 6

B.)
If ∠3 = 5x - 1, and ∠5 = 3x + 11, then the measure of
∠3 = 5x - 1 = 5(6) - 1 = 29
<3 = 29

C.)
If ∠3 = 5x - 1, and ∠5 = 3x + 11, then the measure of ∠1 = 

<1 = <3 = 29 (vertical angles)

D.)
If ∠3 = 5x - 1, and ∠5 = 3x + 11, then the measure of ∠2 =
<2 = 180 - 29
<2 = 151
