Answer: 4
Step-by-step explanation:
solve for the missing angle
the total degrees a triangle can have is 180 so
[tex]180-90-60=30[/tex]
use law of sines to solve for x
[tex]\frac{x}{sin30} =\frac{4\sqrt{3} }{sin60}[/tex]
cross multiply
[tex]sin60*x=4\sqrt{3} sin30[/tex]
divide by [tex]sin60[/tex]
[tex]x=\frac{4\sqrt{3}sin30 }{sin60}[/tex]
type into calculator with (ALPHA Y= for a fraction on TI-84) MAKE SURE IT IS IN DEGREES
