soz i know the pic isnt very good quality but il just write it out if you cant read it kk.
A basket B, containing medical supplies is descending vertically at a constant speed over a point X.
An observer O, notes that at a certain instant the angle of elevation to B is 45 degrees.
At the same instant a second observer, P, standing 80m from O notes the angle of elevation to B is 26 degrees.
Calculate the height of the basket at the instant these measurements were recorded.
