Need help with ALL PROBLEMs Please help Part 2 In the triang

Part 2: In the triangle below, find z and y. 12 Given that sine Hand les in the third quadrant, trigornametrie function find the other five values of 13 For each of the following, draw the referenoe angle and find the eract function value, if it exists: (a) cot (60) b) sec (-270\") (c) cos(495) (d) sin (S) (e) tan(H) 14. Convert 120 to radians. 15. Convert to degrees. 16. Graph each function below, and determine the amplitude, period, and phaae shift

Solution

11. Its a 30-60-90 triangle where hypotenuse=10

therefore shorter side, y=10/2=5

and longer side, x=shorter side sqrt3=5sqrt3

12.sin theta=-5/13

opposite=5 , hypotenuse=13

adjacent=sqrt(169-25)=12

cos theta=-12/13

tan theta=sin theta/cos theta=5/12

cot theta=1/tan theta=12/5

csc theta=1/sin theta=-13/5

sec theta=1/cos theta=-13/12
