intersect at E. If AE = 3, EB = 4, CE = x, and ED = x - 4, what is the

value of x?

- trig -
**Reiny**, Monday, February 1, 2010 at 9:47amyou have similar triangles, so set up a ratio

(x-4)/4 = 3/x

x^2 - 4x = 12

x^2 - 4x - 12 = 0

(x-6)(x+2)= 0

x = 6 or x = -2, but x = -2 makes no sense

so x = 6
