Since supplementary angles are angles that equal to 180, you first need to subtract 40 from 180 to find out what the equation equals. This is the layout of the equation. 140=4x+20. Next you subtract 20 from each side, 120=4x then you divide by 4 four, x=30.
Answer:
That is called a cyclic quadrilateral. Angles E and G add up to 180 degrees and angles H and F add up to 180 degrees.
Supplementary angles are two angles whose measures add up to 180°
