    On the question II (A), I calculated EFP angle to be 26.65 degrees.

    However, on (B), I do not know how to solve the question.

    draw a vertical line from p to the top line. this is the shortest distance.
    this also makes a right angled triangle.
    you know the angle efp and 2.8 metres so use sohcahtoa to work out the opposite side.
