Since angle A = Angle B, I believe you would write it out like this:
6x+12=3x+63
subtract 3x from both sides, then subtract 12 from both sides.
3x=51
divide 51 by 3 to find x.
x=17
Now to find the measure of angle A.
A = 6(17)+12
A = 102+12
A = 114, angle A is 114 degrees.
Answer:216 in^3
Step-by-step explanation:
Length=L
Surface area=216
surface area=6 x L^2
216=6xL^2
Divide both sides by 6
216/6=(6xL^2)/6
36=L^2
L^2=36
Take the square root of both sides
√(L^2)=√(36)
L=6
Volume of cube=L x L x L
volume of cube=6 x 6 x 6
Volume of cube=216
I believe it is A. Sorry if it’s wrong <3
