Answer:

<em>4. lines r and s</em>

Step-by-step explanation:

The angles shown are same side interior angles, so they are supplementary. Their measures add to 180 deg.

5x + 10 + 130 = 180

5x + 140 = 180

5x = 40

x = 8

Lines r and s are cut by a transversal, line l. Angles 3 and 6 are alternate interior angles. Lines r and s are parallel.

Isosceles triangles have two sides that are the same. Whereas scalene triangles have three side lengths that are different.
