You can see the polygon in the attached figure.
It's a trapezoid, so it's not equilateral, nor regular.
Answer:
x = 121°
Step-by-step explanation:
The angle supplementary to 115° is 180 - 115 = 65° and the angle that forms a full circle with 304° is 360 - 304 = 56°. Since the measure of an exterior angle is equal to the sum of its remote interior angles, we know that x = 65 + 56 = 121°.
Answer: 3x + 5y = 15
