Question

Solve for the missing side in the right triangle.
A) 5
B) 12
C) 13
D) 17

Answer 1

C) 13

Explanation:

Using the formula:
`a^(2) +b^(2)=c^(2)`, we can plug in 5 into a and 12 into b, since c is always the hypotenuse. Plug those numbers into the formula:
`5^(2) + 12^(2) =c^(2)` and you get 25 + 144 =
`c^(2)` or 169 =
`c^(2)`. You can then get rid of the square on the c by finding the square root of both sides. So, the square root of 169 would give you the answer of 13.

Answer 2

c) 13

Explanation:

`{a}^(2) + {b}^(2) = {c}^(2) \\ {5}^(2) + {12}^(2) = {c}^(2) \\ 25 + 144 = {c}^(2) \\ 169 = {c}^(2) \\ c = 13`
