# Math Help - Similiar Triangles

1. ## Similiar Triangles

I have a triangle with it's largest side x+3 (AB). The base side is x+5 (AC). The other side doesn't have a length (BC). Point E lies on AC, AE is 5 and EC is x. Line OE is perpendicular to AB and connects to E with a length of 3. Angle ACB equals 90 degrees. Using similar triangles find x. This question was in a Yr 11 Maths Specialist assignment. The only answers I've got is -13 and -8. Please reply quickly.

2. Hello, rhettfraser!

There is obviously a TYPO in the problem . . .

I have a triangle with it's largest side x+3 (AB).
The base side is x+5 (AC). .??

If $AB \:=\:x + 3$ is the longest side, how can $BC\:=\:x+5$ be longer?
