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

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
