Question 564633
BC is a 30-60-90 triangle with a right angle at B. Use the measure of the side given to find the measure of the indicated side.
BC= 20, find AB
:
We can use the tangent of 60 degrees to find side AB
That is: tan(60) = {{{(side opposite)/(side adjacent)}}}
tan(60) = {{{(AB)/20}}}
1.732 = {{{(AB)/20}}}
AB = 1.732 * 20
AB = 34.64
