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

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

Thank you!

you're welcome
