3. Mr. Henley is hiking and spots a very tall cedar tree across a ravine. Interested in the height of the tree he quickly grabs a couple of cones and paces it out. He drops a cone at C and walks 100m along the cliff edge and drops another at point B. At point B he measures the angle of elevation and the angle the BC line makes with the line of sight to the base of the tree. He then goes to point C and does the same. He quickly sketches the diagram below on the back of a granola bar box. How tall is the tree (AD, marked as h) to the nearest tenth of a metre? 77° 52° В 67 100 m
