Cot (B) = Cos(B) / Sin(B)
Cot B * Sin B = cos(B) / Sin(B) * Sin(B) = Cos(B)
Answer: Cos(B)
You first do 26/3, and then press equals, and then multiply the answer by three
<em>It would be $46 because when you add the 15% tax to it, the total is $61. </em>
<em>$61-15%=$46. To check $46+15%=61! Hope i helped! :-)</em>
#4) From the reference angle of 58° we can see that we have the side opposite to that angle as well as the hypotenuse. Recall that sin=opp/hyp so we are going to use sine to find that side
sin(58°) =

(multiply both sides by 19 to isolate x)
19 sin(58°) = x (plug into calculator)
16.1 = x
#5) From the reference angle of 56°, we see that we have the adjacent and the opposite sides. Remember that tan=opp/adj so we will use tangent to find x
tan(56°) =

(multiply both sides by

)

(flip them so x is on the top)
[tex] \frac{12}{tan(56)} = x
8.1 = x
