Answer explanation

First, you need to use the 146 and its supplement to find the missing angle at the top of the triangle. 180-146 is 34. Now I know the triangle has angles with 77 and 34 degrees. When added together, that equals 111. 180-111=69. The missing angle is 69 degrees.

Angle 1 and angle 2 have a ​ (a)   relationship.

• supplementary
• complimentary
• vertical
• alternate interior
• alternate exterior

Solve for x.
