A ladder 8 meters long leans against the wall of a building. if the foot of tha ladder makes an angle of 68 with the ground, how far is the base of the ladder from the wall

Assuming that the wall makes a right angle with the floor, then we have right triangle: wall, floor, ladder.

cos(68)=x/l, where x is the distance between the base of the ladder and wall, and l=8m is the length of the ladder.

Thus:

x=l×cos(68)=8×cos(68)=2.99m= aprox 3m

aprox 3m
