 Roderick F. 1 0 This example is all backwards, I agree with the russian guy. you are solving for sin(a), tan(a) and cos(a)
 Terrance S. 1 0 Kind of screwed up the example there.
 Ruslan B. 2 0 Hello, there seems to be a mistake in this example. The opposite side and the adjacent side are mixed up. You seemed to have used the adjacent side for the opposite and the opposite for the adjacent. sin b should be 9/15 not 6/15 that should be used for cos b and tan b should be 9/6. Please do look into this question. I think that you have solved for Sin (a), Cos (a) and Tan (a) and the example says solve for the b. Just a concerned learner. Thank you.
 Allan A. 1 0 The illustration is, again, incorrect with the word problems.
 Jerry B. 1 0 Pre-Algebra Course, Trigonometry section: In the example for finding sine, cosine, and tangent of angle b, the opposite and adjacent leg values seem to be reversed. Is this an error?
