A UFO is spotted between two towns. The angle of elevation from Town A to the UFO is 32 degrees and the angle of elevation from Town B to the UFO is 27 degrees. If the towns are 21km apart, how far was each town from the UFO?

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

d is the answer
