Answer this in the next 4 min for free An 18-foot ladder is leaning against the side of a building forming a right triangle. The angle formed by the ladder and the ground is 60°. Which is closest to the distance, in feet, of the bottom of the ladder from the base of the wall?

The foot of the ladder is

10

feet away from the base of the wall.

Explanation:

Here , the wall , top and foot of the ladder and ground makes a

right triangle of which length of ladder h=18 is regarded as

hypotenuse angle with ground is

θ=60°;cos 0= b/h or

cos 60°=b/18or b=18.cos 60=18.1/2

=9 feet

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
