To find E, we need to find c first.

The 3 inside angles of a triangle need to equal 180 degrees.

So a + b + c = 180

a = 71, b = 60

Now we have 71 + 60 + c = 180

c = 180 - 71 - 60 = 49 degrees.

Angle C and E are supplementary angles which means they need to equal 180 degrees.

c + e = 180

49 + e = 180

e = 180 -49 = 131 degrees
