7. your friend is standing on top of a building, which is 130 ft. above the ground, looking down at a tree that is 40 ft. away from the base of the building.
what is the angle of depression from the person to the base of the tree? round to the nearest degree. show all work.

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,

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
