Answer:
x = 21
General Formulas and Concepts:
Geometry
- Corresponding Angles - Angles that are congruent to each other and occur with parallel lines
Explanation:
Step 1: Identify
We see that the measures given are Corresponding Angles
Step 2: Solve for x
- Set up equation: 8x - 7 = 9x - 28
- Subtract 8x on both sides: -7 = x - 28
- Add 28 on both sides: 21 = x
- Rewrite: x = 21
