Question

The hypotenuse of a right triangle is 65 m long. If one of the legs is 39 m long, how long is the other leg?​

Answer 1

52 m

Explanation:

(a^2) + (b^2) = (c^2)

(39^2) + (b^2) = (65^2)

(39^2) + (b^2) = (65^2)

1521 + (b^2) = 4225

(b^2) = 2704

b = 52

Answer 2

use Pythagoras theorem to solve this

`C^(2)`=
`A^(2)`+
`B^(2)`

C is always the hypotenuse of a triangle

Explanation:

`65^(2)` =
`39^(2)` +
`B^(2)`

my calculator tells me that..

4225 =1521 +
`B^(2)`

2704 =
`B^(2)`

`√(2704)` = B

52=B

nice .. it worked out to a nice whole number
