Answer:

mDE = 9

Explanation:

mCD and mDE must add up to mCE

Step 1: Set up equation

mCD + mDE = mCE

5x + 1 + 3x + 3 = 20

Step 2: Solve for x

  1. Combine like terms: 8x + 4 = 20
  2. Subtract 4 on both sides: 8x = 16
  3. Divide both sides by 8: x = 2

Step 3: Find mDE

mDE = 3x + 3

mDE = 3(2) + 3

mDE = 6 + 3

mDE = 9
