Question

What is the measure of AngleDCF? Three lines extend from point C. The space between line C D and C E is 75 degrees. The space between lines C E and C F is 54 degrees

Answer 1

129

Explanation:

Answer 2

∠DCF = 129°

Explanation:

We assume that line CE is between lines CD and CF.

The angle sum theorem applies:

∠DCF = ∠DCE +∠ECF

∠DCF = 75° +54°

∠DCF = 129°
