Answer:
Internal angle = 
Number of sides = 18
Step-by-step explanation:
Given that:
We have a regular polygon with number of sides unknown.
Measure of an exterior angle of the polygon = 
To find:
Measure of an interior angle and the number of sides of the polygon?
Solution:
Let us have a look at the relation of sum of external angles.
Sum of one internal angle and its corresponding external angle = 
Internal angle + external angle = 
Internal angle =
-
= 
Sum of all the external of a regular polygon = 
All the external angles will be equal because it is a regular polygon.
Let the number of sides = 
Therefore,

Therefore, the answers are:
Internal angle = 
Number of sides = 18

Answer:
A 34
Step-by-step explanation:
The measure of the angle is 1/2 the measure of the larger arc - 1/2 the measure of the smaller arc
VXY = 1/2( VZ - WY)
= 1/2( 93-25)
=1/2 (68)
=34

Answer:
Angles UWV and UWZ are complementary
Step-by-step explanation:
we know that
If the sum of the measures of two angles is equal to 90 degrees, then, the angles are complementary
so
In this problem

therefore
Angles UWV and UWZ are complementary
