It form a right triangle
legnth of ladder is hypotonuse
bottom of ladder from wall distance is one leg
distance up wall is other leg
a^2+b^2=c^2
c=hypotonuse and a and b are legs
4^2+b^2=20^2
16+b^2=400
minus 16 both sides
b^2=384
sqrt both sides
b=8√6 ft
aprox
b=19.59ft from ground
Answer: 11.8 km
Step-by-step explanation:
The resulting figure is a right angled triangle shown below
The slope-intercept form of a line is the following:
In this form, is the shape and is the y-intercept. Your line written in this form is
which implies that the slope is 5 and the y-intercept is -2.
