Find the answer for m∠EFD

Given:

In triangle DEF, and .

To find:

The measure of angle EFD.

Solution:

In triangle DEF,

          (Given)

It means triangle DEF is an isosceles triangle.

          (Base angles of an isosceles triangle are equal)

Using angle sum property in triangle DEF, we get

Divide both sides by 2.

Therefore, the measure of angle EFD is 41 degrees.
