I’ll mark brainiest or what ever it is called

C and D

Step-by-step explanation:

Choice C says that if you take 180 minus the sum of angles 1 and 2, you will find the measure of angle 3. Choice D says that is you take 180 minus angle 4, you will find the measure of angle 3 due to both angles forming a straight angle.

horizontal translation of 2 units in the positive x direction

vertical translation of 3 units in the positive y direction

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
