Question
A pole 25m long is placed against a vertical wall such that its lower end is 7m from the foot of the wall on the same horizontal ground. If the upper end of the pole is push down by 2m, calculate correct to 2 significant figure: 1) how much further away from the wall the lower end will move; 2) the angle of the pole now makes with the horizontal.

25^2=base^2+vertical^2
on the fist position, calculate the vertical distance up the wall.
Then subtract 2m, then recalculate the new base.
