Which expression represents the approximate length of bc?

Hello from MrBillDoesMath!

BC = 3 * sin (66)/ sin(38)

Discussion:

From the law of sines:

sin(38) /3 = sin(66)/ BC

BC *  (  sin(38)/3 )  = sin(66)        => multiply both sides by BC

BC = sin(66) /  ( sin(38)/3)           => multiply both sides by ( 3/sin(38) )

BC = 3 * sin (66)/ sin(38)

which is the first choice.

image result for what is another name for consecutive interior angles? ​

when two lines are crossed by another line (called the transversal): the pairs of angles on one side of the transversal but inside the two lines are called consecutive interior angles. in this example, these are consecutive interior angles: d and f.
