B5 = -1 x (2 ^ 5 - 1)
B5 = -1 x (2 ^ 4)
B5 = -1 x 16
B5 = -16
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.
