  • Corresponding Angles - Angles that are congruent to each other and occur with parallel lines

Step-by-step explanation:

Step 1: Identify

We see that the measures given are Corresponding Angles

Step 2: Solve for x

  1. Set up equation:                         8x - 7 = 9x - 28
  2. Subtract 8x on both sides:         -7 = x - 28
  3. Add 28 on both sides:               21 = x
  4. Rewrite:                                       x = 21

Answer:

x = 21
