9. the diagonal of a rectangle is 25 in. the width is 15 in. what is the length?

Hello! Your answer is 20 in.

Pythagorean's theorem states that with a right triangle, when a and b are the two sides that form a 90 degree angle, and c is the third side.

In this case, c = 25, and a = 15. We are looking for b. This is because the width and length form a 90 degree angle, so the width and length are a and b, meaning that c must be the diagonal. The diagonal is 25 in, so c = 25, and the width is 15, so either a or b is equal to 15. I just went with a = 15.

Now, substitute these values into the formula.

Therefore, the length = 20, or the length = 20 inches.

Hope this helps!

if you need , reply with more info. u.

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
