Radio towers are used for transmitting a range of communication services including radio and television. The tower will either act as an antenna itself or support one or more antennas on its structure. On a similar concept, a radio station tower was built in two Sections A and B. Tower is supported by wires from a point O. Distance between the base of the tower and point O is 36 m. From point O, the angle of elevation of the top of the Section B is and the angle of elevation of the top of Section A is .
- (i)Find the length of the wire from the point O to the top of Section B.[1]
- (ii)Find the distance AB. OR Find the area of .[2]
- (iii)Find the height of the Section A from the base of the tower.[1]
