A passenger in an airplane at an altitude of 10 kilometers sees two towns directly east of the plane. The angle of depression to the towns are 28 degree and 57 degrees. How far apart are the towns?

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

2, 2, 2 or -4, 20, 29

step-by-step explanation:

there is two ways you can do it.

your answer is

a.

5

step-by-step explanation:

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
