Answer:


AC=9√(3)\ units

Explanation:

see the attached figure to better understand the problem

In the right triangle ABC


sin(60\°)=(AC)/(BC)


sin(60\°)=(√(3))/(2)

so


(AC)/(BC)=(√(3))/(2)

we have


BC=18\ units

substitute


(AC)/(18)=(√(3))/(2)


AC=18(√(3))/(2)=9√(3)\ units

In the triangle below, angle B measures 60° and BC is 18. What is the length of AC-example-1
