A tower T is observed from two points A and B which are 240 metres apart. The angle TAB is found to be 57degree and the angle TBA is 78degree. Find the distance of the tower from A.
Answered by Reiny
You say angle TBA = 78°
This is only possible if A and B are on opposite sides of the tower.
Confirm this before I solve it.
