Question

How do you use the Pythagorean Theorem to solve for the missing sides 15, 25, b?

Answer 1

`b = color(green)(20`.

Explanation:

The Pythagoras theorem goes as follows:

`color(blue)(a^2+b^2 = c^2` , where `c` is the hypotenuse.

Here :`color(blue)(a=15 and c = 25`

`color(blue)(15^2 + b^2 )= 625`
`225 + b^2= 625`
`400= b^2`
`b= sqrt400 = 20`
So, `b = color(green)(20`.
