Question

If Q = 53 cm and P = 28 cm , what is the length of R?

Answer 1

The answer is C. 45cm

Explanation:

Use the Pythagorean theorem to find the length of r.

Answer 2

To get the answer we can use Pythagorean theroem.
We know that
`P^2+R^2=Q^2` /-
`P^2`

`R^2=Q^2-P^2`
Now we can substitute our data.

`R^2=53^2+28^2 \\ R^2=3592 \\ R=60` - its the answer
