Radio towers are typically tall structures designed to support antennas for tele communications and broadcasting, including television. There are 2 main types: guyed and self-supporting structures.
They are among the tallest human-made structures. Masts are often named after the broadcasting organizations that originally built them or currently use them.

On a similar concept, a radio - station tower was built in two sections A and B. From a point 24 m from the base of the tower, the angle of elevation of the top of section A is `30^(@)` and the angle of elevation of the top of section B is `45^@).`


The height of the tower is

A

17.9 m

B

24m

C

31.6 m

D

20 m
