Angles of Elevation and Depression Year 10Trigonometry From a vertical cliff 80 m above sea level, a fishing boat is observed at an angle of depression of 6°. How far out to sea is the boat, correct to the nearest metre? Question 1 metres The angle of elevation to the top of a vertical cliff fromsea level is 18° from a point 2 km from the base of the cliff.Find the height of the cliff, correct to the nearest metre. Question 2 metres From a point 120 m horizontally from the base of a building, the angle of elevation to the top of the building is 34°. Find the height of the building, correct to the nearest metre. Question 3 metres Question 4 The angle of elevation from point A on horizontal ground to the top of a 20 m high pole is 35°. A rope is attached from A to the top of the pole. Find the length of the rope, correct to 1 decimal place metres From the top of a vertical cliff, Jim spots a boat 150 mout to sea. The angle of depression from Jim to the boat is 35°. How many metres (to the nearest whole number)above sea level is Jim Question 5 metres The ramp from one level to the next in a car park is 20 mlong and drops 4 m. Find the angle of depression of the ramp, to the nearestdegree. Question 6 ° |
