(3/4) cups

Step-by-step explanation:

It is given that,

Lindsey's cookie recipe uses 1 1/2 cups of brown sugar to make 2 dozen cookies.

We need to find how much brown sugar should Lexi use to make only 1 dozen cookies.

2 dozen cookies = 1 1/2 cups

= 3/2 cups

For 1 dozen cookies,

So, to make 1 dozen cookies, she will need (3/4) cups of brown sugar

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
