PLEASE HELP ASAP FOR LOTS OF POINTS AND BRAINLIEST

Answer:

x = 55

y = 60

Step-by-step explanation:

If a quadrilateral is inscribed in a circle, then its opposite angles are supplementary. So E and G are supplementary, and H and F are supplementary.

x + 15 + 2x = 180

3x + 15 = 180 combine like terms

3x = 165 subtract 15 from both sides

x = 55 divide both sides by 3

y + 3y - 60 = 180

4y - 60 = 180 combine like terms

4y = 240 subtract 60 from both sides

y = 60 divide both sides by 4
