Two radar stations 2.5 miles apart are tracking an airplane. The straight-line distance between Station A and
the plane is 7 miles. The straight-line distance between
Station B and the plane is 9 miles.
a) What is the angle of elevation from Station B to the
plane?

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
