Question

Find the length of the hypotenuse of a right triangle with legs of lengths 9 and 12. If necessary, round your answer to two decimal places.

Answer 1

use the pythagorean theorem a^2 + b^2 = c^2 so then a = 9 and b = 12 and solve for c

Answer 2

there is one right angled triangle 3,4 and 5 - that slould give u a clue

Answer 3

oh yeah.. okay

Answer 4

the pythagorean theorem says that (leg)^2 x (leg)^2 = (hypotenuse)^2 given that the triangle is a right triangle

Answer 5

dont you do the square root after?

Answer 6

yes to find c since c is squared in the equation

Answer 7

i got 15

Answer 8

you can also find the equation using trig to find the angle the triangle makes and using that to find the hypothenuse

Answer 9

15 is correct
