The average distance from the sun to the planet venus is about 1.08943 x 108 km. The radius of a human hair is about 0.00125 cm. A) what is the distance from the sun to venus written in standard form?
B) what is the radius of a human hair written in scientific notation?
C) In comparing the measurements in parts a and b what must be done before a comparison is made?

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
