Answer:
AC = 18
Step-by-step explanation:
Given the question:
<em>In a right triangle, m∠A = 30° and AB = 12√3 (AB is the hypotenuse). How long is AC?</em>
Side AC is adjacent to angle A. Then, by definition of cosine:
cos(A) = adjacent/hypotenuse
cos(A) = AC/AB
AC = cos(A)*AB
AC = cos(30°)*12√3
AC = 18
