QUIZ 8 SOLUTIONS #1: The remaining side, by Pythagorean Theorem, is 4. Therefore: sin 4/5 cos 3/5 tan 4/3 csc 5/ 4 sec 5/ 3 cot 3/ 4 θ θ θ θ θ θ = = = = = = #2: a) We want an angle that terminates at the same point as 440°. So we subtract a full circle, 360°, and get 80° b) We’re looking for an angle θ in the second quadrant. The acute angle 25° that forms our reference angle, will be 180°-25°= 155° #3: tan37 , tan 26.5 1000

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
