Elaine is 28 years older than Carly. Elaine is x years old. Carly is y years old. Which set of equations shows this situation? *
O x = y + 28, y = x + 28
x = y + 28, y = x - 28
x = y - 28, y = x + 28
O x = y - 28, y = x - 28

answer: i think it's a

step-by-step explanation:

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
