Susan marciano invested part of her 10,000 bonus in a fund that paid 10% profit and invested the rest in stocks that suffers a 3%loss find the amount of each investment if her over all net profit was 480

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
