Question

What is the length, in inches, of the hypotenuse of a right triangle with a leg that is 9 inches long and a leg

that is 2 inches long?
a. √22
b.77
c. 185
d. 5.5
e.11

Answer 1

Well, the formula is a^2 + b^2 = c^2. Put your numbers in your equation. 9^2 + 2^2 = c^2. Now simplify the left side. 85=c^2. Now find the square root from both each side. The answer is =~9.22. But I don’t see the answer, sorry

Answer 2

To find the hypotenuse use the formula c=√a²+b². Also it doesn't matter which numbers replaces a or b, just remember that the hypotenuse is always the greatest number.

c=√9²+2²

c=√81+4

c=√85≈9.22 inches
