draw a diagram. Review your basic trig functions.
PT cot68 = (PT-20) cot28
A flag pole and a building stand on the same horizontal level from a point P at the bottom of the building the angle of elevation of the top T of the flag pole is 68 degree.From the top Q of the building the angle of elevation of the point T is 28 degree.If the building is 20m high calculate; distance PT and height of the flag pole

I misread the problem. If we label the bottom of the pole B, then
BT cot68 = (BT-20) cot28
Both those expressions give BP, the distance between the building and the pole.
To get PT, then,
PT^2 = BP^2 + BT^2
BT cot68 = (BT-20) cot28
Both those expressions give BP, the distance between the building and the pole.
To get PT, then,
PT^2 = BP^2 + BT^2
pls someone should help me solve it
