Hi! can some explain how to evaluate these two questions, so that i can understand how to complete them?
1. given: cos∅= -4/5, sin x= -12/13, ∅ is in the third quadrant, and x is in the fourth quadrant; evaluate cos(theta - x).
2. given: sin∅= -3/5, ∅ is a third quadrant angle, and tanф= -7/24, ф is a second-quadrant angle; find tan(∅+ф).
you for your !

Ican interpret and represent the remainder in division calculations sensibly for the context (eg 27.4 in calculating average height in cm: $27.44 if it represents an amount of money) solve the following problems. 15) the wildlife park charges $25.50 dollars per person to enter their park if the park made $15096 dollars today, how many people entered the park? 16) ms adams plus 2,230 other keen runners ran a marathon: between them they ran 94817.5km. how many km did each competitor run?
