Asked by Cherie

I have to determine the unknown length of a right triangke to the nearest tenth of a unit. One side is 7m and the base is 10m. I got a friend to do this and age came up with 7.1m as the answer. When I do the steps I get the answer 12.21. I believe my friend is right but need help with the steps on how to figure this out. Thank you!

Pythagorean Theorem

a^2 + b^2 = c^2

7^2 + 10^2 = c^2

49 + 100 = c^2

149 = c^2

12.21 = c

Pythagorean theorem

side^2 + side^2 = hypotenuse^2

7^2 + 10^2 = 49 + 100 = 149

I would agree with you.
