Given cos  A  5 7 and cos  B  7 9 , using the sum and difference identities determine the value of sin  A  B (You may assume angles A and B exist in the first quadrant) a. 14 6  20 2 63 c. 10 6  28 2 63 b. 14 6  20 2 63 d. 10 6  28 2 63

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

what i would say the best answer is a. 40.5

i would say b) is your answer

sorry if im wrong
