triangle ABC is a right triangle with angle C=90 deg. AC=3sqrt3 and angle B =30 deg. Find AB and BC. HERE IS WHAT I HAVE :) BC= 6 sqrt3 Angle B=30 deg Angle C= 90 Deg which means angle A= 60 degrees b= 3 sqrt 3 I need help finding BC, I got lost in all my scribbles

Here is a quick sketch of your triangle. |dw:1355094411875:dw| I actually did a set of videos about this a while ago...

tan(30)=3sqrt(3)/BC BC=3sqrt(3)/tan(30) BC=9
