Question

Joe has a small pond on his farm.He wants to build a footbridge from point A to point B.He marked a spot at point C so that angle B is a right angle.

What is the approximate distance from point A to point B?

A.23 ft

B.24ft

C.25ft

D.26ft

Answer 1

It must be 24ft, because to be integer values it must be a 7-234-25 triangle.

Answer 2

Not 234, 24.

Answer 3

Which means that because the hypotenuse must be 25, the AB side must be 24.

Answer 4

That help any?

Answer 5

yup thx very much

Answer 6

You know the families of right triangles, right?

Answer 7

yea

Answer 8

O.K. then. Just for anyone out there that doesn't know them, they're triplets of numbers that work for the Pythagorean triples.

Answer 9

ok thc

Answer 10

Some of them are 3-4-5, 7-24-25, and 8-15-17.

Answer 11

The biggest number is always the hypotenuse.

Answer 12

Meaning the side opposite the right angle.

Answer 13

Just a shortcut for using the Pythagorean Theorem.

Answer 14

Which is a^2+b^2=c^2, where a and b are legs and c is the hypotenuse (duh!)
