Direction: Draw a picture that illustrates the situation. 1. A tree casts a shadow 15 feet long. The angle of elevation of the sun is 63°. 2. Rhombus LOVE have diagonals LV and OE. The measure of LLOV is 102° and the measure of each side is 12 centimeters. 3. A ramp has a slope 4. A man at the edge of the cliff 100 meters above the sea level observes that the angle of depression from his position to a boat at sea is 19°. 5. Sophia and Rebeka leave their house at the same time. Sophia walks on a direction of N 22° E while Rebeka walks on a direction N 112° E. Direction: Solve each of the following problems. Round off your final answers to the nearest hundredths. 1. The angle of elevation of the sun is 35°. How long is the shadow cast by a building 94 meters high? 2. A nipa hut is directly below a helicopter. If a man in the helicopter sees a carabao 45 meters from the nipa hut at angle of depression 20°, how far from the ground is the helicopter? 3. An electric post was broken by a super typhoon. It formed a right triangle with the ground. If the broken part made an angle of 290 with the other part, and the topmost part of the post of the post which was on the ground was 8 meters from the base, how tall was the post?
