Given:
u and v are parallel lines.
To find:
The value of x.
Solution:
If a transversal line intersect the two parallel lines, then
(1) Corresponding angles are congruent.
(2) Same sides interior angles are supplementary angles and their sum is 180 degrees.
15.
(Corresponding angles)



Therefore, the value of x is 4.
16.
(Same sided interior angles)



Divide both sides by 2.


Therefore, the value of x is -6.
