Question

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

Answer 1

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.
