Step-by-step explanation:
Since both lines are parellel,
Angle q = angle b ---------1
Angle p = angle c ---------2
Angles in a straight line at a point sums up to 180°
Angle q + angle a + angle p = 180°
Angle b + angle a + angle c = 180° ----- (from eq 1 and 2)
2 right angles = 2 × 90° = 180°
Angle b + angle a + angle c = 2 right angles
I hope you find the answer useful.
