The angles of a quadrilateral are x, 5x + 15 degrees, 3x - 25 degrees, and 4x - 20 degrees. Find the measure of the largest angle of the quadrilateral.

Since we know it is a quadrilateral that would only mean that it has a total degree of 360....and we know that each of these angles added up will equal 360 so your equation is....

$\LARGE{(x)+(5x+15)+(3x-125)+(4x-20)=360}$ Simplify to find x and what you find for x you would input with x and you will find the largest angle....
