Question

A spotlight is attached to the ceiling 2 feet from one wall of a room and 3 feet from the wall adjacent. How many feet is it from the intersection of the two walls?
a. 4
b. 5
c. 3 square root of 2
d. square root of 13
e. 2 square root of 3

Answer 1

if you can picture this, it forms a rt triangle with the shortest leg 2, the longer leg 3, and you are looking for the hypotenuse.


So, h^2 = 2^2 + 3^3
h^2 = 4 + 9
h^2 = 13
h = sqrt 13

Answer 2

Thank you!
