what is the measure of ∠dcf? the measure of ∠dcf is degrees.
Answer
Explanation:
Step1: Identify angle - addition property
The measure of $\angle DCF$ is the sum of the two adjacent angles $\angle DCE$ and $\angle ECF$.
Step2: Add the angle measures
$\angle DCE = 75^{\circ}$ and $\angle ECF=54^{\circ}$, so $\angle DCF=75^{\circ}+ 54^{\circ}$. $75 + 54=129$
Answer:
$129$
