30 points! Find the length of side x in simplest radical form with a rational denominator.

Answer:
2 sqrt(3) = x
Step-by-step explanation:
We know that
sin theta = opp side / hypotenuse
sin 60 = x /4
Multiply each side by 4
4 sin 60 = x
We know
sin 60 = sqrt(3) /2
4 * sqrt(3) /2 = x
2 sqrt(3) = x
Answer:
2sqrt(3)
Step-by-step explanation:
cos(30) = adjacent/hypotenuse
sqrt(3)/2 = x/4
x = 4 × sqrt(3)/2
x = 2sqrt(3)
sqrt: square root
