y=27

Step-by-step explanation:

Fact 1: The sum of two adjacent angles formed by the intersection of two lines is 180.

So, x+146=180

=>x=34

Fact 2: The sum of the inscribed angles in a triangle is 180.

So, (5y+3)+(4y+8)+34=180

=>5y=180-45

=>5y=135

=>y=27

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
