Question

ab, eg, fa, and fb are shown such that ab || eg and fa and fb are transversals. given that m∠ecf = 125°, complete the statement. the m∠acd is _, because ∠ecf and ∠acd are _. 55° 70° 125° complementary angles supplementary angles corresponding angles vertical angles

Explanation:

Step1: Identify angle - type relationship

$\angle ECF$ and $\angle ACD$ are vertical angles. Vertical angles are formed when two lines intersect and are congruent.

Step2: Determine the measure of $\angle ACD$

Since $\angle ECF = 125^{\circ}$ and $\angle ECF$ and $\angle ACD$ are vertical angles, $m\angle ACD=m\angle ECF = 125^{\circ}$.

Answer:

$125^{\circ}$, vertical angles
