I was doing the problem attached, but cannot understand what is meant by E 70 S. Can someone please help me out. the Answer should be 13.57.
I also attached the sketch diagram.
For this problem E 70 S refers to a bearing which I think is east 70 south, or in translation a bearing of 70 degrees from either the south or east axis in either clock-wise or counter-clockwise direction.
However, the diagram doesn't indicate that either of the above are correct.
Hi chiro, the diagram attached is sketched be me, so it can be incorrect. I searched on the net for bearings and i found the picture attached. The E 70 S is most probably referring to the angle between 90 and 60. But still, i don't know which is the angle of descent which will result to 13.57.
