Question

Help is needed!!! please

Answer 1

5

Explanation:

There are 2 ways to look at this. I will explain both.

First we have the 3-4-5 triangle method, stating that any triangle with sides 3 and 4 will have the last side as 5.

Now, for the more complex way of doing this, we can use the Pythagorean theorem to solve this problem.

Pythagorean theorem:
`a^2+b^2=c^2`

We can use 4 for a and 3 for b

You will now have

`4^2+3^2=c^2\\\\16+9=c^2\\25=c^2`

Then take √25, or 5.
