Given: sin(A) = 2/3 We will need the value of cos(A) so use the identity: cos(A) = +-sqrt(1 - sin^2(A)) We are given that A is in the 2nd quadrant, therefore, we chose the negative value for the cosine: cos(A) = -sqrt(1 - sin^2(A)) cos(A) = -sqrt(1 - (2/3)^2) cos(A) = -sqrt(1 - 4/9) cos(A) = -sqrt(5/9) cos(A) = -sqrt(5)/3 …
