Answer:

35.28°

Step-by-step explanation:

Sine rule:

[tex]\boxed{\frac{sin\angle A}{a} =\frac{sin\angle B}{b}=\frac{sin\angle C}{c} }[/tex]

Given:

∠A = 68°

a = 6.1

b = 3.8

∠B = x

Therefore:

[tex]\displaystyle \frac{sin68^o}{6.1} =\frac{sin(x)}{3.8}[/tex]

[tex]\displaystyle sin(x)=\frac{3.8\times sin68^o}{6.1}[/tex]

[tex]sin(x)=0.556[/tex]

[tex]x=35.28^o[/tex]
