Answer:
20 sides
We know that if we find the size of an exterior angle for the given regular polygon whose exterior angle is 18∘, we can find the number of sides. Where, n is the number of sides. Therefore, there are 20 sides in the given regular polygon whose exterior angle is 168∘.
Answer:
x<29
Step-by-step explanation:

Answer:
Options (C) and (E).
Step-by-step explanation:
Rotation is a rigid transformation in which size and shape of the figure and image remains the same.
That means angles and sides of the triangles given in the figure will remain same after the transformations given.
Since, the given triangle has been rotated about a point Z, each rotation will share the vertex Z.
And every figure is the transformed form of the given triangle, all four triangles will be congruent.
Options (C) and (E) are the correct options.
