Question

This is matematics course and it's trigonometric functions unit. Please help me solving these questions. I would be really thankful if there's solution provided especially on thinking and application part. Thank you so much whoever helps me...    Image transcriptions

Knowledge 1) Sketch a neatly labeled diagram of the given angle in standard position. Determine the related acute angle. a) 0 = 150 13 12 2) Using the diagram, state the following ratios a) cote = b) sin 0 = c) sec 0 = 3) The point (-6, -7) is on the terminal arm of an angle &amp; in standard position a) Sketch the principle angle . b) Determine the related acute angle, to the nearest Degree c) Determine the principle angle

Application 4) Use special triangles to determine the exact value of the following ratio. Show all steps! Draw and label the special triangle that you used to determine each ratio a) 2 sin? 60 x tan 30&quot; 5) Two ropes are attaches to the top of a flagpole and nailed down in the grass. Angelo is looking at the flagpole and notices that the rope on the left of the flagpole is 12 m long and makes a 50 angle with the ground. The other rope is on the right of the flagpole and makes a 40 angle with the ground. How long is the rope on the right side of the flagpole, to the nearest tenth of a metre? Include a neatly labeled digram

b) sin &amp; cos 0 tan 0 = 1 - cos? 0 /3 Communication 7) Explain why 0.7071067812 is not the exact value of cos 45* /2 8) Explain how the CAST rule is used to determine the exact value of cos 210 /2
