Question

Two parallel lines are cut by a transversal such that one of the interior angles is 57. Find each of the
interior angle .

Answer 1

Answer:

Let the interior angle be a and b

a=57

Angle A +Angle B =180...... ( sum of interior angle is supplementary)

57+b = 180

b = 180— 57

b = 123°

The measurement of Angle B is 123°
