Thank you soo much @heather2292 I'll give u a medal :)

Answer 4

So, do you know how to solve that?

Answer 5

You use Pythagorean theorem for this.
A^2 + B^2 = C^2
This is for right triangles, C is the hypotenuse, the diagonal line.
If it's _ feet from the house, you fill in _^2 +B^2 = C^2
(I'm on a mobile device so I can't go back to see the problem lol sorry) whatever the other side of the right angle is, fill it in for B. Square the two numbers and add the products. So if it's 3^2 + 4^2 = C^2 you get 9+16=C^2 which is 25=C^2 so finally you find the square root of 25 which is 5, which is your hypotenuse.

Answer 6

So? Someone else could be looking for help with this and that might help them.
