Answer:
d = 69°, e = 32°, f = 79°
Step-by-step explanation:
the 69° angle and d are vertical angles, so d is 69°.
same with e and the 32° angle, so e is 32°.
the 69° angle and f are on a straight angle, which means they, and e, add up to 180° when combined.
69 + 32 = 101
180 - 101 = 79
so f is 79°.
