Finding triangle sides given height and base

[tony700]

I have figured out the triangle's height and base, but I need to figure out sides a and b. I have tried Pythagorean theorem and similar triangle ratios, but it is not working out. Please help. See picture below. Thank you.View attachment 6489

We have that two right triangles and from the Pythagorean Theorem for those two we get:
$$464^2+e^2=a^2$$ and $$464^2+(1218-e)^2=b^2$$

From the Geometric mean theorem we have that $$464^2=e\cdot (1218-e)$$

Now we have three unknown variables, $a,b,e$, and three equations. So, we can find the values for $a,b,e$.

Is the angle contained by $a$ and $b$ equal to $90^\circ$? For that matter, what is the complete problem?
