Question

Note: Triangle may not be drawn to scale.Suppose a=48 and b=55 and c=73.Find an exact value (report answer as a fraction): sin(B)=cos(B)=tan(B)=sec(B)=csc(B)=cot(B)=

Answer 1

From the drawing above :

• Sin (B) = opp/hyp = (b /c )= 55/73

,

• Cos (B) = adj / hyp =(a/c ) = 48 /73

,

• Tan(B) = opp/adj = (b/ a) = 55/48
