Question

In a right triangle, the hypotenuse is 17 inches and a leg is 15 inches. Find the length of the third leg.

Answer 1

Multiply 17^2 and 15^2. subtract 15^2 from 17^2. Next find the square root. Did you get an answer of 8?(:

Answer 2

17^2 - 15^2 = b^2
b = 64^2 = 4096
4096 should be your answer.

It's the pythaogrean theorem correct?
So a^2 + b^2 = c^2
Vice versa
OR
c^2 - b^2 = a^2
c^2 - a^2 = b^2

Notice that if you have the hypotenuse which is C, then you always subtract either the a^2 or the b^2 to find the other value.

Answer 3

Fang02, I believe you are wrong because if you check your answer 15^2+8^2=17^2.
225+64+289.
