If bcde is congruent to opqr then line de is congruent to explain.

qr i took the test

bc go to op and de go to qr

congruent means if two seperate square have points the points on the top can connect to the other squares top to make a cube

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

answer: idk
