We apply the pythagorean theorem to find this answer.
a = 11 and b = 6 are the given legs
c = unknown hypotenuse
So,
a^2+b^2 = c^2
c = sqrt( a^2+b^2 )
c = sqrt( 11^2 + 6^2 )
c = sqrt( 121 + 36 )
c = sqrt( 157 )
c = 12.52996 approximately
c = 12.5
Side note: once you replace 'a' and b with 11 and 6, you can compute everything with a calculator in one single step more or less. The steps above are shown if you wanted to find the exact value sqrt(157).
Easy remember (x^m)(x^n)=x^(m+n) basically add exponens when the base is same (13^-11)(13^16)(13^-3)(13^4)(13^-5)= 13^(-11+16-3+4-5)= 13^(5-4)= 13^1=13
