Question

Find EF in the trapezoid.

How can I solve for this?

Answer 1

Ef=52

Explanation:

By the mids segment theorem if a line sgement has endpoints on the midpoints of 2 sides of a triangle then it is half the size of the third side.

That means

2(4x+8)=9x-5

8x+16=9x+5

11=x

Then plug it back in to EF

4(11)+8

44+8

52
