 Question 180867: Ok, this deals with angles of elevation and deppression in triangles. -A plane leaves a runway and rises to a height of 3078. At theat point it is 6000 feet from its point of take off. Find the angle of elevation form the plane to its take off. I have so far figured out that is would use the SIN funtion and have set up the equation- S SIN x=3078/6000 but I am confused as to how to proceed to solve it?
