Answer:
We can start by using the tangent function and the information in the problem to set up two equations.
Step-by-step explanation:
Let's call the height of the pillar h.
tan(45) = (h+5)/x -> x = (h+5)/1.732
tan(60) = h/x -> x = h/1.732
Since x is the same distance in both equations, we can set them equal and solve for h.
(h+5)/1.732 = h/1.732
h=5*1.732 = 8.66
The height of the pillar is 8.66m.
