Question

Find the length of the unknown side. Round your answer to the nearest tenth.

14.0
13.0
12.5
11.5

Answer 1

The correct option is: 11.5

Explanation:

Suppose, the length of the unknown side is

So, here the length of hypotenuse is 14 and the lengths of other two sides are 8 and .

So, the length of the unknown side is 11.5

Answer 2

The correct option is: 11.5

Explanation:

Suppose, the length of the unknown side is
`x`

So, here the length of hypotenuse is 14 and the lengths of other two sides are 8 and
`x`.

As the given triangle is right angle triangle, so using Pythagorean theorem, we will get.........

`8^2+x^2= 14^2\\ \\ 64+x^2=196\\ \\ x^2=196-64=132\\ \\ x=√(132)=11.489...\approx 11.5`

(Rounded to the nearest tenth)

So, the length of the unknown side is 11.5
