20. The illustration shows a plane taking an aerial photograph of point A. Because the point is directly below the plane, there is no distortion in the image. For any point B
not directly below the plane, however, the increase in distance creates distortion in
the photograph. This is because as the distance from the camera to the point being
photographed increases, the exposure of the film reduces by (sin )(csc 0 - sin o).
Express (sin )(csc o - sin e) in terms of cos O only.

i know the answer is 3

step-by-step explanation:

$18 was the price of the t-shirt

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
