8 meters

Step-by-step explanation:

First, let's find the scale factor by dividing the value of the corresponding sides.

20/15 = 1.33...

This means that the scale factor is 1.3

To find the length of the missing side, multiply the length by the scale factor.

6(1.3) = 8

Therefore, the value of side c is 8 meters.

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

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
