**STEPS:**

EXAMPLE 1: Angle 1 and angle 2 are ** adjacent angles**. Angle 1 measures 42 and the two angles together add to 132. How big is angle 2 and what is its type?

**STEPS:**

EXAMPLE 2: Angle 1 and angle 2 are complementary angles. Angle 2 measures 3 more than 2 times the measure of angle 1. How big is angle 2 and what is its type?

EXAMPLE 3:

Angle 1 and angle 2 are vertical angles. Angle 1 measures 12x + 15 and angle 2 measures 7x + 35. Find x and the measure of angle 1?
