If mâ 4 = (3x)â° and mâ 8 = (x + 40)â°, what is the measure of â 4? â 4 and â 8 are vertical.

this is not the answer this is just a question. is this middle school math?

step-by-step explanation:

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
