Engineers use three-dimensional coordinates to design construction projects. An overhead light is anchored at point (7, 12, 10) in a design where the floor of the building is represented by the two-dimensional coordinate plane (x-axis and y-axis). Measurements are in feet.
Lights are spaced from the hanging light, 4 feet away in the x-direction and 4 feet in the y-direction. Select the possible coordinates of the anchors for two other lights.

ash2326 · Answer

(x, y, z)= ( 7, 12, 10)
lights are spaced from the hanging light 4 feet away in x and 4 feet away in y directiom
so add 4 to x and y cordinate or subtract 4 from x and y coordinate of overhead light
(7-4,12-4,10)= (3, 8, 10)
(7+4, 12+4, 10)= (11, 16, 10)
option A
