Step-by-step explanation:

[tex] \sin(20) = 3 \div x[/tex]

Multiply both sides with x :

[tex] x \times \sin(20) = 3[/tex]

And divide both sides with sin(20) :

[tex]x = 3 \div \sin(20) = 8.771[/tex]

Which gives us x=8,771

Answer:

AB = 6

Step-by-step explanation:

sin 20° = 3/?

[tex]\frac{1}{2}[/tex] = [tex]\frac{3}{x}[/tex]

cross-multiply: x = 6
