Question 177580: In triangle ABC , measure angle A equals 30 dregrees and measure angle C equals 90 degrees. Find AB if BC equals 8. Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! 30 60 90 right triangle
proportion of sides: shortest 1, hypotenuse 2, middle sqrt(3) Memorize this! It is used on the SAT tests all the time!
BC is the shortest.
AB is the hypotenuse which is 2 times the shortest (see line 2)
So AB=8*2=16
