Find b and c, with showing your work.

AB = 90 degrees

AC = 60 degrees

Step-by-step explanation:

Since every triangles angles equal to 180 you first subtract 30 from 180 which is 150 degrees. You can see there is a square around a vertex which means that angle is 90 degrees. Now subtract 90 from 150 which is 60 degrees. So the last angle is 60 degrees.

10 * 563.67 = 5636.7

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
