Answer:
Supplementary angle; x = 14.
Step-by-step explanation:
Angle (9x - 2) and angle (10y + 6) form a straight line, so they form a supplementary angle.
Because angle (9x - 2) and (5x + 54) are corresponding angles, we can set them equal to each other.
9x - 2 = 5x + 54
9x - 5x = 54 + 2
4x = 56
x = 14.
