Question #1: A guy wire is 13.5 m long. It supports a vertical power pole. The wire is fastened to the ground 9.5 m from the base of an 8.7 m tall pole. Calculate the measure of the guy wire and the ground. Question #2: A 5.0 m ladder is leaning 3.7 m up a wall. What is the angle the ladder makes with the ground? Question #3: A kite has a string 100 m long anchored to the ground. The string makes an angle with the ground of 68 degrees. What is the horizontal distance of the kite from the anchor? Question #4: A ladder is leaned 10 m up a wall with it's base 6 m from the wall. What does the ladder make with the ground? Question #5: The acronym SOHCAHTOA is often used in trigonometry. What do you think each letter stands for and give an example finding either an unknown side or an unknown angle using a portion of this acronym. This here I have no idea. (1) In this problem, we are asked to find the measure of the angle between the guy wire and the ground Let the angle be θ cos θ = 9.5/13.5 = 0.7037 θ = 45.28 or 45° 16’ 30” (2) Let the angle made by the ladder with the ground be θ sin θ = 3.7/5 = 0.74 θ = 47.73 = 47 43’ 53” (3) Let the horizontal distance be x cos 68 = x/100 x = 100 * cos 68 = 37.46 m (4) Let the angle be θ tan θ = 10/6 = 1.667 θ = 59.04 = 59 2’ 10” (5) The acronym SOHCAHTOA stands for “Silly Old Harry Couldn't Answer His Test On Algebra” It is recommended as a mnemonic to the students of Trigonometry to remember the formulas for the three primary trigonometric ratios, sin, cos and tan Sin = Opp/Hyp, Cos = Adj/Hyp, Tan = Opp/Adj
