During one year, people in the u. s. older than 18 years old watched a total of 342 billion hours of television. the population of the u. s. older than 18 years old was about 209 million people.
on average, how many hours of television did each person older than 18 years old watch that year? round to the nearest hour.
on average, how many hours per week did each person older than 18 years old watch that year? round to the nearest hour.
i need on the part b i don't understand how people are getting 52, but i know you have to divide 1636 and 52 but how do you get 52

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.

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
