In the right triangle shown B=60 and AB=4V3 how long is BC plz help

Answer:
x = 2√3.
Step-by-step explanation:
We know the measure of angle B and the length of the hypotenuse so we need to use the cosine function (cos = adjacent/hypotenuse).
cos 60 = x / 4√3
x = 4√3 * cos 60
x = 4√3 * 1/2
x = 2√3.
