Math Problem Statement
Solution
To solve for and , we first use the fact that . In parallel lines cut by a transversal, corresponding, alternate interior, or supplementary angles are related.
Observations:
- Angle Relationships:
-
The angle ° is a vertical angle to °, so they are equal:
-
The angle ° and ° are consecutive interior angles (or supplementary), so:
-
Step 1: Solve for
From the vertical angle equation: Simplify:
Step 2: Solve for
Substitute into the supplementary angle equation: Substitute :
Final Solution:
