At a point A on the ground the angle of elevation of a mountain due east is 16.6°, and at B, due south of the mountain, the angle of elevation is 12.3°. If the mountain is 960metres high, find the distance from A to B, correct to one decimal place
(Note: I think I have to draw this, I can't visualise on a flat diagram/scale diagram where point B would be-Is it a 3-D shape?). Could you please help me and explain to me what the diagram. Thankyou.
PS: Could you please email me what the diagram (where the points should go). I can't work it out. Do I put a dot in the middle for the base of the mountain, a dot to the left of it at the horizontal called A, a dot a few cm's underneath the base of the mountain called B and a dot directly above the base of the mountain which is the top of the mountain? Where is the 12.3 degrees? Please help. Thankyou.
