Question

What is the measure of Angle D F E?

Triangle DF E. The exterior angle to angle F is 28 degrees.
28 degrees
62 degrees
118 degrees
152 degrees

Answer 1

A 28

Explanation:

Took test 152 is wrong. Went looking for right answer.

Answer 2

152 degrees

Explanation:

we know that

Exterior angle is supplementary to interior angle. Their sum is equal to 180 degrees

so

`m\angle DFE+28^o=180^o`

`m\angle DFE=180^o-28^o=152^o`
