X= 3x + 6 / 3 = 6 (im pretty sure)
Answer:
72 degrees.
Step-by-step explanation:
If the angle is x degrees its complement is 90-x degrees and it's supplement is 180-x degrees.
4(90-x) = 2/3(180 - x)
360 - 4x = 120 - 2/3 x
360 - 120 = -2/3 x + 4x
240 = -2/3 + 12/3 x
240 = 10/3 x
x = 240 * 3/10
x = 72 degrees.
The surface area of the box will be 112 in²
Explanation
According to the given diagram, the shape of the box is Right Rectangular prism.
The formula for the surface area is :
, where 
length, 
width and 
height of the rectangular prism
Given in the diagram that, 
So, plugging the values into the formula...
So, the surface area of the box is 112 in²
I think it is equivalent to 16
hope that helps! :)
