<PRE><B>Question 608534</B>
A spotlight is 5 feet from one wall of a room and 10 feet from the other wall at right angles to it. How many feet is it from the intersection of the two walls?
----
Let the walls be the x and y axis of a coordinate system.
Plot a point at (5,10)
---
Find the distance of the point from the origin.
---
d^2 = 5^2 + 10^2
d = sqrt(125)
d = 5*sqrt(5)
d = 11.18
