Question

Find the length of the missing side. Leave your answer in simplest radical form.

Answer 1

Explanation:

1) learn the Pythagoras theorem which is
`a{2} +b{2} =c{2}`

2) to work out the longest length you do
`4^2+3^2` which is 25

3) than you do the square of 25 which is 5 so the answer is 5
