Which methods could you use to calculate the x-coordinate of the midpoint of a horizontal line segment with endpoints at (0,0) and (20,0) Check all that apply.

A. Count by hand.

B. Divide 20 by 2.

C. Divide 0 by 20.

D. Divide 20 by 0.

A. Count by hand.

B. Divide 20 by 2.

Step-by-step explanation:

The midpoint between two points is found by the mean of their coordinates.

Endpoints at (0,0) and (20,0)

So we have x coordinates of 0 and 20. Their mean is:

So we can find both counting by hand, or dividing 20 by 2.

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

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
