two parallel lines are crossed by a transversal. what is the value of a? a = 43 a = 63 a = 117 a = 137
two parallel lines are crossed by a transversal. what is the value of a? a = 43 a = 63 a = 117 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)
