Answer 3

The opposite angles of a cyclic quadrilateral add up to 180.
A cyclic quadrilateral is a quadrilateral with the four vertices on a circle.

y + (3y + 8) = 180
y + 3y + 8 = 180
add the y terms:
4y + 8 = 180
subtract 8 from both sides:
4y = 180-8 = 172
divide both sides by 4
y = 172/4 = 43

Angle R = 3y + 8
Put y = 43 and calculate R.
