Math Problem Statement
Solution
In this problem, we are given that lines , meaning they are parallel, and we need to find the values of and .
Step 1: Recognize angle relationships due to parallel lines
Since the lines and are parallel and a transversal cuts across them, the angles labeled and form corresponding angles. Corresponding angles are equal when the lines are parallel.
Thus, we can set up the equation:
Step 2: Solve for
We solve the equation: Subtract from both sides: Subtract 2 from both sides: Divide both sides by 4:
Step 3: Solve for
Since and are alternate interior angles (which are equal when the lines are parallel), we can write: Substitute into this equation:
