Question

find the measure of the missing angles.
answer
attempt 1 out of 3
d =

e =

f =

Explanation:

Step1: Find the measure of \(d\)

Since \(d\) is a right angle, \(d = 90^{\circ}\)

Step2: Find the measure of \(f\)

\(f\) and \(69^{\circ}\) are supplementary angles (they form a linear - pair). So \(f=180^{\circ}-69^{\circ}\)

$$f = 111^{\circ}$$

Step3: Find the measure of \(e\)

\(e\) and \(69^{\circ}\) are vertical angles. Vertical angles are equal. So \(e = 69^{\circ}\)

Answer:

\(d = 90^{\circ}\), \(e = 69^{\circ}\), \(f = 111^{\circ}\)
