Answer:
c = 8.54
Explanation:
Use Pythagorean theorem and sketch a right triangle with side lengths of 8 and 3, with the hypotenuse labeled as x.
Use the formula a² + b² = c²
8² + 3² = c² Plug in your two numbers into variable
64 + 9 = c² Simplify the squared numbers
73 = c² Add them together
√72 = c Divide the squared variable by using the opposite operation, square rooting
c = 8.54 Plug number into calculator and round
