Question

question 1. find the measure of angle ecg.

Explanation:

Step1: Identify right - angle

Assume the right - angle shown is 90°.

Step2: Analyze angle ECG

There is no other information given about sub - angles within the right - angle related to ∠ECG. If we assume the right - angle is divided into two equal parts and one of them is ∠ECG, then ∠ECG = 90°. But without more information from the figure (such as angle markings or relationships), if we consider the whole right - angle as ∠ECG, then ∠ECG = 90°.

Answer:

90°
