- Polygon B has 4 sides and one pair of parallel sides and it is a quadrilateral because it has 4 sides.
- Polygon C has 6 sides and so is not a quadrilateral but a hexagon and it has a pair of parallel sides.

57° is the answer
A triangle adds up to 180° , a circle adds up to 180°
T = 126 °
S = 180° - 126°
S= 54°
R = 69°
Q + S + R = 180°
69 + 54° = 123°
=180° - 123° =
Q= 57°
Use the Pythagprean theorem:

We have:
