Answer:

∠CDF= 70°

Step-by-step explanation:

there's an easier way to do this which is adding the angles ∠EDG and ∠GDF and then subtracting that from 180° but, checking your work in the same process is a little more work.

First, I'd like to find ∠ADB.

  1. 85°+70°= 155°
  2. 180°-155°= 25°
  3. ∠ADB= 25°

Second, add all the angles together.

  1. 70°+50°+60°+85°+25°= 290°
  2. 360°-290°= 70°
