180-(55x2)=70
Those two angles are the same... I forget the name of the law that states it, but that's the answer... x=70
Y=2(given)
-2=12x-3+10
-2=12x+7
-9=12x,
-3/4=x
The volume would be V = (side of base)^2 * (height). The height would be 3. To see this, make yourself a model if need be. Assuming that the dimensions of the "square piece of cardboard" are x by x, then the length (or the width) of a side of the square bottom would be x-3-3, or x - 6.
So: V = (x-6)^2*3 = (area of base)*(depth of box)
= 3(x-6)^2 (answer)
Answer:
79°
Step-by-step explanation:
Line pu is a straight line meaning it has a measure of 180°.
37+34+30=101
180-101=79
