HELP PLEASE :). 1. While the earth's orbit (path) about the sun is slightly elliptical, it can be approximated by a
circle with a radius of 93,000,000 miles.
a. How far does the earth travel in one orbit about the sun? That is.
what is the approximate circumference of the earth's path?

Step-by-step explanation:

a) The circumference is given by the following expression:

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
