Review Ex 1 – Trig Word Probs. A captain of a boat stands on deck with a digital hypsometer looking at a land beacon. The hypsometer gives an angle of elevation reading of 18. 50 and a direct distance reading of 0. 44 miles. How far from the beacon is the boat?
Review Ex 2 – Trig Word Probs. Jim stands in a tree looking at Susie with an angle of depression measuring 700. The point in the tree where Jim is standing is 12 feet off the ground. How far would Jim have to throw a pebble if he wanted to hit Susie? Assume the pebble travels in a straight line path.
Review Ex 3 – Trig Word Probs. Sampson aims his sling shot at Goliath’s head with an angle of elevation measuring 620 and hits him square between the eyes. How far from Goliath’s feet is Sampson standing if Goliath is 23 feet tall? Round to the nearest tenth of a foot.
Review Ex 3 – Trig Word Probs. Sampson aims his sling shot at Goliath’s head with an angle of elevation measuring 620 and hits him square between the eyes. How far from Goliath’s feet is Sampson standing if Goliath is 23 feet tall? Round to the nearest tenth of a foot. 12. 2 feet away
Review Ex 4 – Trig Word Probs. A ship’s navigator observes the measure of the angle of elevation to the top of a cliff, that the boat is headed directly towards, to be 640. An hour later, traveling straight at the cliff, he noticed the angle of elevation has 0 changed to 79. How far has the shipped moved if the cliff is 75 meters tall?
