Jill is standing at the base of her apartment building. She measures the angle of elevation to the top of a nearby tower to be 40º. Then Jill goes to the roof of her apartment building, directly above her previous position, and measures the angle of elevation to the top of the same tower to be 30°. If the height of the tower is 100 meters, the height of Jill's apartment building is how many meters?

other answer is correct. i had used the radius of the radius somehow. a website:

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140

both triangles are similar because 2 is just smaller than the big one 1 is similar because they are facing different way's but are similar to each other

step-by-step explanation:

-3.5 is the distance.

i've had this question so choose the one in the absolute value sign.
