Answer:
<RPU = 20 degrees
<y= 140 degrees
Step-by-step explanation:
<STU = 60 degrees ( In a Cyclic quadrilateral opposite <'s sum to 180)
Therefore <RPU = 180-60-100
= 20 degrees (Angle sum in a triangle = 180)
Triangle QPV is isosceles and base angles in an isosceles are equal so <QVP = 20 degrees.
Thus <y = 180-20-20
= 140 degrees.
