What is the description of < 2 as it relates to the situation shown?

.
a.< 2 is the angle of depression from the airplane to the radar tower.

b.< 2 is the angle of elevation from the airplane to the radar tower.

c.< 2 is the angle of elevation from the radar tower to the airplane.

d.< 2 is the angle of depression from the radar tower to the airplane.

For this problem your answer is most likely C

The answer is C. But let me explain to you why.

For letter A, this is not true. If your are talking about the angle of depression of the plane, that would be ∠1.

For letter B, this is not true  because angle of elevation would indicate the the tower is higher than the airplane, which is obviously impossible.

For letter D, this is the opposite of letter B. Angle of depression would mean that the airplane is below the tower.

I hope my explanation helped you in your understanding of this problem :)

X= 2 he can buy 2 packs of cards for $12 and an action figure for $3 so he would spend $15 in total plus the free poster
