The bottom of a 13-foot straight ladder is set into the ground 60 inches away from a wall. When the top of the ladder is leaned against the wall, what is the angle of elevation made by the bottom of the ladder and ground? ​

what do you need me to answer?

step-by-step explanation:

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
