Question

given that m∠ecf = 125°, complete the statement. the m∠acd is 125 because ∠ecf and ∠acd are vertical angles.

Explanation:

Step1: Identify angle - type relationship

Vertical angles are equal.

Step2: Determine the measure of ∠ACD

Since ∠ECF and ∠ACD are vertical angles and m∠ECF = 125°, then m∠ACD=125°.

Answer:

125
