Answer:

B = 87

Step-by-step explanation:

The Attached Pic includes Sine Law which can be used in any Triangle

So for our Question

we have A=33 , a=6 , b=11

by Applying Sine Law

[tex]\frac{sin(A)}{a} =\frac{sin(B)}{b}[/tex]

Then

[tex]sin(B)=\frac{b*sin(A)}{a} =\frac{11sin(33)}{6}=0.9985\\ B=sin^{-1}( 0.9985)=87[/tex]
