All angles in a triangle add up to 180 degrees. So, if you are missing an angle, add up the degrees of the angles present and subtract that from 180. That will be the value of the missing angle in degrees.
186.46 for a triangle you go base x height/2 and then add area of the square

Actually Welcome to the Concept of the Areas and Volumes.
We know that, Area of a Rectangle = length * Width.
Since,here Length = 6 inch and Area = 54 square inches,
==> Width = Area / length
==> Width = 54/6
=> Width = 9 inches.
Hence the width of the rectangle is 9 inches.

integrate to get
![[ln|t|]^{3x}_x=ln|3x|-ln|x|=ln| \frac{3x}{x}| =ln |3|=ln(3)](https://tex.z-dn.net/?f=%5Bln%7Ct%7C%5D%5E%7B3x%7D_x%3Dln%7C3x%7C-ln%7Cx%7C%3Dln%7C%20%5Cfrac%7B3x%7D%7Bx%7D%7C%20%3Dln%20%7C3%7C%3Dln%283%29)
this only is true when x>0
when x turns negative, we get -ln(3) because of math
4x10 6th power = 280
1x10 4th power =13
So if I'm right 4x10 6power is greater
