A board with a length of 15 feet is leaning against a vertical wall. The angle that the board forms with the ground is 53.13°. You are finding the distance from the bottom of the board to the wall.

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

1/2*qr*rs

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

the answer is su.k.my? ? co.kc
