You will need to use the Pythagorean Theorem, which basically says the following relationship between the two legs and the hypotenuse of a right triangle:
(leg1)2+(leg2)2=(hypotenuse)2(leg1)2+(leg2)2=(hypotenuse)2
Thus, substituting the given values you mentioned yields
72+242=x272+242=x2
where xx represents the unknown value, the hypotenuse.
Solving for xx yields the expression x=242+72−−−−−−−√=25x=242+72=25.
(leg1)2+(leg2)2=(hypotenuse)2(leg1)2+(leg2)2=(hypotenuse)2
Thus, substituting the given values you mentioned yields
72+242=x272+242=x2
where xx represents the unknown value, the hypotenuse.
Solving for xx yields the expression x=242+72−−−−−−−√=25x=242+72=25.
