Answer: 7.81
Step-by-step explanation: a^2 + b^2 = c^2 this is the Pythagorean Theorem
which means if you square the first two numbers and add them together you will get the last number squared
so in this case 6 squared in 36 and 5 squared is 25
25 + 36 = 61 so then just find the square root of 61 which is 7.81
