Question

Find the unknown side of the right triangle ring my answer to the nearest tenth if necessary

Answer 1

We are given a right triangle and two of its sides. We are asked to determine the hypotenuse. To do that we will use the Pythagorean theorem:

$h^2=a^2+b^2$

Where:

$\begin{gathered} h=\text{ hypotenuse} \\ a,b=\text{ sides} \end{gathered}$

Now, we substitute the values:

$h^2=15^2+20^2$

Solving the squares:

$h^2=225+400$

Adding the values:

$h^2=625$

Now, we take the square root to both sides:

$h=\sqrt{625}$

Solving the square root:

$h=25$

Therefore, the value of the hypotenuse is 25.
