Mark is out for a walk on a beautiful day along the floor of a flat valley. He spies a distant mountain, and he'd like to know how far up he would have to climb (without actually climbing it). From where he stands, he measures its peak to be at an angle of elevation of 37.3° on a bearing of 260°. Mark then walks exactly due Southwest for 1 kilometer along the valley (a bearing of 225°) and takes another look at the peak of the mountain. This time, it's at an angle of elevation of 50.4° on a bearing of 340°. Mark is good with trigonometry. He knows how much higher the mountain is than he is. Do you know? How much does the mountain rise above the valley floor? The answer is approximately 700m. No shape given.
