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

Respuesta :

Answer:

3.00 m to the nearest hundredth.

Step-by-step explanation:

We solve this using the trigonometry of a right triangle:

The hypotenuse = 8 m and we need the adjacent side, so:

cos 68 = adj/hyp = x / 8  where x , the adjacent side = the distance  of the ladder from wall.

x = 8 cos 68

= 2.997 m
