Both angles WILL have the same measure.
So,
3x-10= x+40 (you have to set the equations equal to one another)
Now, add 10 to both sides.
3x=x+50
Subtract x on both sides.
2x=50
Divide both sides by 2.
x=25
Now, plug in x.
(25 +40)= 65
(3(25)-10)= 65
x equals 25 and both angles are equal to 65. Or "B".
I hope this helps!

I think they need to get more than 120 cans
complementary is 90 degrees. so, you combine like terms.

P= perimeter. x= # of inches. 4=number of sides in a square
P= 4x
so, P= 13.4 x 4. Therefore, the perimeter is 53.6 inches.
