Question

Find the length of the hypotenuse if a = 5 and b = 7. Round to the nearest tenths.

Answer 1

8.6

Explanation:

To find the length of a hypotenuse, use the formula a²+b²=c² where c is the hypotenuse. In this case, it's 5²+7²=c². Then do the calculations and take the square root to find c. 25 + 49 = c². 74=c². The square root of 74 to the nearest 10th is 8.6
