<PRE><B>Question 176211</B>
The angle of elevation e from A to B and the angle of depression d from B to A. Find the measure of each angle.
e: (7x-5) degrees, d: 4(x+7) degrees 
--------------
The two angles are equal.
7x-5 = 4(x+7)
7x - 5 = 4x + 28
3x = 33
x = 11
----------------
Angle size = 7x-5 = 7*11-5 = 72 degrees
