Use the system of equations below to solve for z. 7x+3y+2z-4w=18
4w+5x-3y-2z=6
-2w-3x+y+z=-5
2z+3w+4y-8x=11

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

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
