Geometry ProblemsExcercises (Contains Trigonometry ~ Grade 9 standard) 5. A square of side length 12cm is placed inside a circle so that each of the corners touches the circumference of the circle. Find the area of the shaded region to 2 decimal places. 6. In the rectangle shown, ST and UQ are perpendicular to PR. Given PQ = 18 and QR = 12, find: (a) Length of UR (b) Area of the Parallelogram TQUS. 7. The bearing of a buoy from the end of a jetty (Point A) is 320° and the bearing of the same buoy from the other end of the jetty (Point B) is 338°. The jetty is on a NorthSouth line, that is A is due North of B. The distance between the points A and B is 150 metres. Calculate the distance of the buoy from point A correct to the nearest metre. 8. A ship leaves an island and sails on a bearing of 130° for 150km and then on a bearing of 250° for 320km. If the ship is to return to the island sailing on a direct course, (a) How far does it have to travel? (b) What bearing should it sail on? 9. A man is observing a yacht at sea from the top of a cliff. The angle of depression of the yacht from the top of the cliff is 44°. If the yacht, from its current position, sails a further 200 metres away from the cliff, the angle of depression is now 38°. How high is the cliff? Give your answer to the nearest metre.
