Find the measure of the missing angles.
ryzh [129]

Answer:

d = 69° , e = 32° , f = 79°

Step-by-step explanation:

d and 69° are vertically opposite angles and are congruent , so

d = 69°

e and 32° are vertically opposite angles and are congruent , so

e = 32°

69° , e , f lie on a straight line and sum to 180° , that is

69° + 32° + f = 180°

101° + f = 180° ( subtract 101° from both sides )

f = 79°
