Answer the questions by drawing on the coordinate plane below. You may need to print the test and graph the images by hand. (a) Draw the image of △QRS after a rotation of 180° about the origin. Label the image △Q^' R^' S^'.
(b)Draw the image of △QRS after a reflection across the x-axis. Label the image △Q''R''S''

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

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
