The usual trap
Name the opposite and adjacent sides from the angle the question gives. Working from the other acute angle swaps sine and cosine.
Try three questions
Pick an answer to check it and see why. Practice sets also have grid-ins, where you type the answer.
02Question 2
Medium
In a right triangle, angles A and B are the two acute angles. If sin A = 0.6, what is cos B?
03Question 3
Hard
In right triangle MNP, angle P is the right angle and MN = 51. If sin M = (3x − 1)/17 and cos N = (2x + 2)/17, where x is a constant, what is the area of triangle MNP?
