Math Problem Statement
Solution
This image represents two parallel lines and , intersected by a transversal. The angles at the intersection are given as:
- on line
- on line
The question asks to find the value of .
Since the lines and are parallel, the angles formed by the transversal crossing the two parallel lines are corresponding angles. Therefore, we can set the two angle expressions equal to each other:
Now, let's solve for :
So, the value of is .
