Question

Find the hypotenuse.
(4 Points)

Answer 1

a²+b²=c²

5²+12²= c²

25+144=c²

169=c²

`√(169 =) √(c)`

13=c

Answer 2

x = 13

Explanation:

Using Pythagoras' identity in the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² = 5² + 12² = 25 + 144 = 169 ( take the square root of both sides )

x =
`√(169)` = 13
