Aweather balloon is launched from the ground at a spot 250 yards from a 65 foot royal palm tree. what is the minimal angle of elevation at which the balloon must take off in order to avoid hitting
the tree? assume that the balloon flies in a straight line and the angle of elevation stays constant.

incomplete question. how do you expect anyone to you when you do not post the question in its entirety?

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

43
