LJ 130 40 50 Line n intersects lines p, q, r and s, forming the indicated angles. Which two lines are parallel 35 r and s p andr p and a q and r 2

Sagot :

Lines p and r are parallel!

Explanation:

The angle formed at the intersection of line n and line p is measured as 130. The other angle downwards of angle 130 measures 50, because angles on a straight line equals 180. That is;

130 + x = 180

x = 180 - 130

x = 50

Angle x (50) is corresponding to the one at line r, since they're both formed at the same point on both line segments.

Corresponding angles are equal.

That makes line p and line r to be parallel.
