Step-by-step explanation:

Remark

This is just the reverse of the question you just did. This time you are trying to solve for c

Givens

  • a = 8
  • b = 11
  • c = ??

Solution

c^2 = a^2 + b^2        Substitute the givens.

c^2 = 8^2 + 11^2       Expand

c^2 = 64 + 121           Combine the right side by adding

c^2 = 185                   Take the square root of both sides.

sqrt(c^2) = sqrt(185)       Complete the operation

c =  13.601                   Round to the nearest 1/100 th

c = 13.60                      Note: the zero must be there or the answer does not show the nearest 1/100 th
