Tim rode 8 miles due north, then 3 miles due east. How far, to the
nearest mile, is Tim from where he started?

c = 8.54  

Step-by-step 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
