QUIZ 8 SOLUTIONS #1: The remaining side, by Pythagorean Theorem, is 4. Therefore: sin4/5 cos3/5tan4/ 3 csc5/ 4sec5/ 3 cot3/ 4θθθ==#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 θin the second quadrant. The acute angle 25° that forms our reference angle, will be 180°-25°=155°#3: tan37, tan 26.51000hh
