The sum of the angle measures in a quadrilateral is 360 degrees.
2a%2B3a%2B6a%2B7a+=+360

Solve for a and use the answer to find the measure of the largest angle.

The sum of the angle measures in a pentagon is 540 degrees.
x%2B2x%2B3x%2B4x%2B5x+=+540

Solve for x. (Note in this problem that is all they ask you to do...).
