Group Title
An electricity tower is h metres high. The elevation angles of the tower from Aaron and Kevin are respectively 45° and 30° . On the ground, relative to the tower the bearings of Aaron and Kevin are respectively SW and SE. If the boys are 50m apart, find the height h of the tower to the nearest ontenth of metre.
Can someone please explain, I'm so lost xD

you are right.

from first two diagrams we get AT = h and KT = \[h \sqrt{3}\] so from 3rd figure AT2 + KT2 = 2500 so on simplifying h = 25 m

the first 2 diagrams are 2 dimensional and the 3rd figure is an overhead view

So its wrong ?

the figure is somewhat like .... try cutting a pyramid with a square base from one corner of base to it's opposite corner symmetrically. then u get a figure similar to what we need (not exactly similar but good enough to understand the above problem)

it can be in 3D ?

no no u don't need 3d trig. just consider each triangle at one time to get the required variables

Okay, but is it necessary though to draw it ?

the whole point is to test whether u can imagine the required diagram once u get the diagram it is easy simplification. u can see that i used the first two diagrams to get the values of AT and KT in terms of h and then used pythagoras theorem in the final triangle. drawing the diagram is important unless u can visualize it exactly to solve the problem in ur head
