Math Problem Statement
Solution
To solve for the angle in this problem, let’s go through the steps.
Since the lines and are parallel and both are intersected by the transversal , we know certain angle relationships apply.
- Identify the Corresponding Angles: The angle labeled is an exterior angle to the upper intersection point of line and transversal .
- Use Alternate Interior Angles: Because and are parallel, the angle labeled has a corresponding angle on line which is equal to it by the alternate interior angles theorem. This means angle is also .
Conclusion: The measure of angle is .
