The sum of the sides of a quadrilateral is equal to 360º.
x= 4th angle measurement 

We have the following equation:

90+156+28+x=360
x=360-90-156-28
x=86

Answer: the size of the 4th angle would be 86º.

The sum of angles in a quadrilateral = 360 degrees.

Let the fourth angle be x:

Therefore:  90 + 156 + 28 + x = 360

274 + x = 360

x = 360 - 274

x = 86

x = 86°

I hope this helps.

The volume of a cylinder is

V=hpr^2 in this case h=40, r=20/2=10, and we will approximate pi as 3.14 so:

V=40(3.14)(10^2)

V=12560 ft^3
