Question

What is the measure of ∠E? Enter the correct value. Do not enter the degree symbol.

Answer 1

45 degrees

Explanation:

Since this triangle is isosceles, we know that the other angles, D and E, are both 45 degrees because of the sum of interior angles of a triangle always equaling 180 degrees.

Answer 2

To find < E we use tan

tan E = opposite / adjacent

DF is the opposite

EF is the adjacent

DF = 11

EF = 11

tan E = 11/11

tan E = 1

E = 45

Hope this helps
