In the diagram below, DE = AE, BA || CE, CB || DA andmZB= 116°. Find mZE. What is it?

In The Diagram Below DE AE BA CE CB DA AndmZB 116 Find MZE What Is It class=

Sagot :

DE = AE

BA || CE CB || DA B = 116° E = ?

B and D = 116°

the angle next to D measures 180 - 116 = 64°

Angles inside the triangle ADE

Angle A = 64° and angle D = 64° because it is an isosceles triangle.

So E = 180 - A _ D

E = 180 - 64 - 64

E = 180 - 128

E = 52°
