In real right trianlge you would try to find the length by the pythorean theorem.
c%5E2-a%5E2=b%5E2 or c%5E2-b%5E2=a%5E2
Do the smae here. letting a= x+14 and b = x
%2826%29%5E2-%28x%29%5E2=%28x%2B14%29%5E2
676-x%5E2=x%5E2%2B28x%2B196
2x%5E2%2B28x-480
x%5E2%2B14x-240
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x=%28-14%2B-sqrt%28%2814%5E2%29-4%2A1%2A-240%29%29%2F%282%2A1%29
Simplfy
you get two solutions.
x=-24 or x=10
10+14=24 (a side)

Hence, the two sides are 10cm and 24 cm.
