: The last type of shape were given is a quadrilateral. That's when there's 4 sides, but they're all different in legnths, right? Here's the question: The measure of one angle of a quadrilateral is twice the smallest angle;the third angle is 20 degrees greater than the smallest angle;and the fourth angle is 20 degrees less than twice the smallest angle. Find the measures of the 4 angles of the quadrilateral.

Answer by Paul(988) (Show Source): You can put this solution on YOUR website!
The quad adds up to 360 degrees
Equation:
One angle = 2x, third angle = 20+x, fourth angle = 2x-20
(2x)+(20+x)+(2x-40)+(x)=360
Can you solve from there?
Paul.
