This could be anything. What kind of triangle? The description gives you enough to find x.

%281%2F2%29x%284%2B2x%29=60
x%282%2Bx%29=60
x%5E2%2B2x-60=0

x=%28-2%2Bsqrt%284%2B4%2A60%29%29%2F%282%29
x=%28-2%2B2%2Asqrt%2861%29%29%2F2
highlight%28x=-1%2Bsqrt%2861%29%29, which is also the base.
Use this if you want, to compute the altitude. That is all you can do.
