interior angles

Question

A convex pentagon has the following measurements for its interior angles: (x - 8)°,(3x-11)°,(x+8)°, (x)°, and (2x+7)°. Which of the following could be measurements for interior angles of the pentagon? Select all that apply.

Answer 1

The total (in degrees) of all interior angles is (n-2)•180 with n=5 in the case of a pentagon.

That's 540 degrees totaling 8x-4.

 

Solve for x: 8x - 4 = 540.  Then evaluate each of the five individual expressions (which I added) to get the exact measure, in degees, of those five angles.
