Question 633321
A mason wants to be sure he has a right angle corner of a building's foundation. He marks a point 3 ft from the corner along one wall and another point 4ft from the corner along the other wall. If the corner is a right angle, what should the distance be between the two marked points?? 
----
"c" is the hypotenuse.
---
a^2 + b^2 = c^2
3^2 + 4^2 = c^2
9 + 16 = c^2
c^2 = 25
c = 5 ft,
