Answer to Problem 17PSB
Thevalue of xis
Explanation of Solution
Given information:
Line a is parallel to line b.
A
Calculation:
Parallel postulate states that through any given point not on a line there passes exactly one line parallel to that line in the same plane.
By Parallel postulate, draw line mparallel to line a.
If lines are parallel then there interior
Line a is parallel to line b.
By transitive property, we get
Line m is parallel to lineb.
If lines are parallel then there interior angles are congruent.
The value of x is:
