A pilot is flying over a straight highway. He determines the angles of depression to two mileposts, 7.2 mi apart, to be 36° and 44°, as shown in the figure.

B
NOTE: The picture is NOT drawn to scale.
Find the distance of the plane from point A.
distance from A = 5.11
x mi
Find the elevation of the plane.
height = 3.00
mi

This are the answer that I find for A and height they are wrong. I kinda confused why is wrong. Can someone explain to me?? ASAP?!!!

Astudent is determining the influence of different types of food on the growth rate of spiders. she feeds one group of spiders two caterpillars twice a week. the other group received similarly-sized beetles twice a week. she records the amount of time required for individuals to reach sexual maturity. her hypothesis is that the spiders feeding on caterpillars will have a faster growth rate because caterpillars have a higher protein content compared to beetles. in this experiment, what is the dependent variable? spiders assigned to different feeding groups. time required to reach sexual maturity number of prey items fed twice a week. growth rates of each group.
