Answer:
y = 130°
Step-by-step explanation:
4x + 8 + x + 7 + 3x - 19 = 180 (all angles in a triangle add upto 180)
8x = 184
x = 23°
3x - 19 + y = 180 (supplementary = 180)
sub x = 23 into equation
50 + y = 180
y = 130°
The side length of the cube will only go up by a factor of 2.
Think about it like finding the volume of a cube in reverse:
If we multiply the left and right sides of this equation by 8:
And try to "distribute" the 8 by splitting it up into three 2's:
We can see the side length only doubles.
