two parallel lines are crossed by a transversal. what is the value of a? o a = 43 o a = 63 o a = 117 o a = 137
Answer
Explanation:
Step1: Identify angle - relationship
When two parallel lines are cut by a transversal, corresponding angles are equal. Angle (a) and the (63^{\circ}) angle are corresponding angles.
Step2: Determine the value of (a)
Since corresponding angles are equal, (a = 63).
Answer:
(a = 63)
