Question 878543
{{{a^2}}} + {{{b^2}}} = {{{c^2}}} where a and b are sides of a right triangle, and c is the hypotenuse.
You're given the 2 sides.
7 squared + 13 squared = c squared
49 + 169 = c squared
218 = {{{c^2}}}
Take the square root of each side
c = 14.76482
Rounded to the nearest inch, c = 15"
