You have $3,500 on a credit card that charges a 22% interest rate. If you want to pay off the credit card in 3 years, how much will you need to pay each month (assuming you don't charge anything
new to the card)?

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

i those same problems in math and dont know how to do them
