Our angle of interest for the exercise will be the angle that measures 60.26(. We will find out 3 facts about this angle for each of the two similar triangles. The sine of angle B, denoted sin(B) or sin B, is the ratio . The cosine of angle B, denoted cos(B) or cos B, is the ratio . The tangent of angle B, denoted tan(B) or tan B, is the ratio .
