Use the definition of sine as opposite side divided by hypoteneuse. For this problem, the length of side AB equals 2 times the sine of angle C.
abx=cy. x=cy/(ab)

The variable c times the variable b simply equals cb. Just as the variable x times the variable y would equal xy, and so on.
C minus B equals AB
3y=ab. Divide by 3 to get y=ab/3
Here are some rules that can help you simplify such expressions, in some cases. (ab)c=abc abac = ab+c ab/ac = ab-c
the midpoint of AB.
ab = 8-cDivide both sides by ba = (8-c)/b
to solve ab=c+a for a:Divide both sides by b, so:a= (c+a)/b
AB = 2 x 4 (8) C = 3 D = 5

Difficult to tell when you cannot use parentheses. a*(b+c) or a(b+c) = ab + ac This is known as the distributive property of multiplication over addition.
