Answer:
y = 2
Step-by-step explanation:
If one side of a triangle inscribed in a circle is a diameter of the circle, then the triangle is a right triangle and the angle opposite the diameter is the right angle.
Therefor
53y - 16 = 90
add 16 to both sides
53y = 106
Divide both sides by 53
y = 106/53
y = 2
