We dra a rt. triangle.
X = Hor. side = Dist. from foot of ladder to wall.
Y = Ver. side.
Z = Hyp. = 6 m. = Length of ladder.
X = Z*cos63 = 6*cos63 = 2.72 m.
A 6m ladder leans against a wall. The foot of the ladder is placed at an angle of elevation at 63 degrees with the ground. How far is the foot of the ladder from the wall?
