    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.

    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?
