Question

find the measure of the missing angles. answer attempt 1 out of 2 d = ° e = ° f = °

Explanation:

Step1: Identify angle d

The symbol indicating a right - angle is shown at angle d. So, d = 90°.

Step2: Identify angle e

The 100° angle and angle e are vertical angles. Vertical angles are equal. So, e = 100°.

Step3: Identify angle f

The 100° angle and angle f are supplementary (they form a straight - line, 180° in total). So, f=180 - 100 = 80°.

Answer:

d = 90°
e = 100°
f = 80°
