Answer 1

Answer:

d= 90 degrees

e= 99 degrees

f= 81 degrees

Step-by-step explanation:

To find d, you know that the other side is equal to 90. Because two sides that are opposite of each other must be equal to 180, you do 180-90 which is 90 to get d. Therefore, d=90 degrees. 99 degrees and e are alternate interior angles so that means they have to be the same. Because f is on the other side of 99 degrees and two sides that are opposite of each other must equal 180 degrees, you have to do 180-99 which is equal to 81 degrees. Therefore, d=90 degrees, e=99 degrees, and f=81 degrees

Answer 2

Answer:

D = 90° | E = 99° | F = 81°

Step-by-step explanation:

99 degrees and E are the same.

D is a right angle, so 90°.

F is below 99°, so you subtract 99° from 180° to get 81°.

D = 90°

E = 99°

F = 99°
