Activity 7: My Part Find the missing part of a right triangle using the trigonometric ratios. Show and write your solution in a sheet of paper. 1. An anti- aircraft tank targets an enemy helicopter flying at an altitude of 1,600 feet. If the ground distance between the tank and the helicopter is 950 feet, what angle of elevation must the cannon be raised to it the target? 2. At a certain time of the day, the angle of elevation of the sun is 38°. Find the height of a tree whose shadow is 30ft long. 3. A road as a decline of 15°. After driving 15 000 ft along this road, find the horizontal distance travelled.
