Question

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

Answer 1

Answer:

The correct option is:  11.5

Step-by-step 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

Answer:

The correct option is:  11.5

Step-by-step 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.........

$8^2+x^2= 14^2\\ \\ 64+x^2=196\\ \\ x^2=196-64=132\\ \\ x=\sqrt{132}=11.489...\approx 11.5$

(Rounded to the nearest tenth)

So, the length of the unknown side is 11.5
