Emily is saving money for college. She invests $2000 at a 6% interest rate with Wells Fargo Bank. What is the total amount of money she will have in her bank after 3 years?

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
