Answer:
Step-by-step explanation:
The angle marked x° is an inscribed angle that subtends an arc shown as 70°. The inscribed angle is half the measure of the arc:
x° = 70°/2
x° = 35°
__
The angles marked x° and y° are the acute angles of a right triangle, so are complementary.
y° = 90° -x° = 90° -35°
y° = 55°
