Answer:

Step-by-step explanation:
4 is greater than 3
sqrt15 is greater than sqrt6
So 4+sqrt15 must be greater than 3+sqrt6
Assuming that the triangle is a right triangle, we can reverse engineer the Pythagorean theorem (a^2+b^2=c^2).
60^2 + x^2 = 61^2
3600 + x^2 = 3721
x^2 = 3600 - 3721
x^2 = 121
x = sqrt121
x = 11
