You have a total of 35 coins. The number of nickels are less than the number of dimes.
If you have a total of $2.65, how many of each coin do you have?

i think it is 70

step-by-step explanation:

the first option is the answer.

i think the answer is b

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
