Step-by-step explanation:
So,
Angle e = Angle a, as they are alternate angles
Angle f = Angle c, as they are alternate angles
Angles a, b, and c all add up to 180° as they are all on a straight line (straight lines qual 180 degrees)
So, therefore, angles e, f and b all add up to 180° because all triangles equal up to 180 degrees in side
