Question

a right triangle has a hypotenuse measuring 13 centimeters and one leg measuring 5 centimeters. What is the lenght in centimeteres , of the leg of the right triangle?

Answer 1

12 cm

Explanation:

Answer 2

12 cm

Explanation:

So the Pythagorean Theorem states
`a^(2) +b^(2) =c^(2)`

If we know what c and a are, we can solve for b by doing

`b = \sqrt{c^(2) - a^(2)}`

or

`b = \sqrt{{13^(2)-5^(2)}`

`b = √(144)`

`b = 12`
