If you were to invest $400 at 2% interest compounded annually or each year, what would be your balance at the end of the second year? Round to two decimal places.

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

the answer is d.x= 90°

y= 50°

arc lm= 100°
