Question

A vertical pillar stands on the plain ground and is surmounted by a flagstaff of height 5m. From a point on the ground, the angle of elevation of the bottom of the flagstaff is 45° and that of the top of the flagstaff is 60°.Find the height of the pillar.(Use root3 =1.732)

Answer 1

Answer:1.83m

Step-by-step explanation:

Answer 2

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.
