7.) A man is in a boat that is floating 175 feet from the base of a 8.) John wants to measure the height of a tree. He walks 200-foot cliff. What is the angle of depression between the cliff exactly 100 feet from the base of the tree and looks up. The and the boat? angle from the ground to the top of the tree is 33" . How tall is the tree? 9.) The flagpole in front of CB East casts a shadow 40 feet long 10.) Kelly is flying a kite to which the angle of elevation is when the measurement of the angle of elevation to the sun is 70". The string on the kite is 65 meters long. How far is the 31". How tall is the flagpole? kite above the ground? 1 1.) A straight waterslide is 175 feet above ground and is 200 12.) From a 200-foot observation tower on the beach, a man feet long. What is the angle of depression to the bottom of the sights a whale in difficulty. The angle of depression of the slide? whale is 7'. How far is the whale from the shoreline?Directions: Write the letter of correct answer on your answer sheet: 1. Triangle with no equal sides a. isosceles triangle scalene triangle b. equilateral triangle d. oblique triangle 2. An angle larger than 180 degrees is a. Acute angle b. Reflex angle obtuse angle d. Right angle 3. Two angles are complementary. One angle measures (2x - 25). The other angle measures (8x + 5). Which equation should you use to solve for measures of the angles? a. (2x - 25) + (8x + 5) = 90 b. (2x - 25) + (8x + 5) = 180 c. 180 - (2x - 25) - (8x + 5) = 0 d. 90 + (2x - 25) + (8x + 5) = 0 4. Two angles are supplementary. One angle measures (x + 5). The other angle measures thrice the amount. What equation could be used to solve for x? a. 180% = (4x + 20) c. 180 = (3x + 15) b. 180 = 2(x + 5) d. none of the above 5. Which of the following angles is a coterminal angle of 45. a. 360 b. 295 c. 315. d. 4150 6. Which quadrant does 480 falls? a. I b. II &. III d. IV 7. What is the measure in degrees of the angle ? a. 120 b. 210 c. 240 d. 300 8. What is the measure in radians of the angle 1240? 62n 52n a. b. 9 3 9. What is the measure in radians of the angle -880? 42n b. - 44n a. 9 9 10. What is the measure in degrees of the angle - 4050 b. 3040 5040 d. 4040
