Answer:
r = 5
Discussion:
2r + 6 + 3r = 31 => (Given)
(2r + 3r) + 6 = 31 => (combine r terms). Subtract 6 from both sides
5r + 6 -6 = 31 - 6 = 25 =>
5r = 25 =>
r = 25/5 = 5

Answer:
4. Let the number of sides be n
As we know that sum of exterior angles of a regular polygon = 360°
Number of sides = Sum of exterior angles/Each interior angle
= 360°/24°
= 15
Hence, the regular polygon has 15 sides
10. Non-Perpendicular Intersecting Lines
When two lines intersect, they create vertical angles, sometimes called opposite angles, that are congruent.
