Each one uses the law of sines: a/sin(A) = b/sin(B), where A is the angle opposite of a and B is the angle opposite of b. Note that sin(90) = 1, which makes using laws of sines very easy when the side you need to find is opposite the right angle because c/sine(90) = c.

for sine law to find b, you'll need that

anonymous · Answer

can you show me  sine  tan and cos?
