The graph shown below represents a ladder leaning against a wall. The bottom of the ladder is 4 feet from the wall, and the top of the ladder reaches 20 feet above the ground. A graph titled Ladder Leaning Against Wall has Feet from Wall on the x-axis and Feet above Ground on the y-axis. A line goes through points (0, 20) and (4, 0).
What is the slope of the graph?
–24
–20
–5
–4

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

the answer is 13/48
