Answer:
The answer is 3,240
Step-by-step explanation:
In geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon's interior angles is 3240 degrees.
In mathematics, the interior angles of a polygon are the angles on the inside of the polygon created where the sides of the polygon meet. When a polygon is a n-sided regular polygon, meaning it has n sides, its sides have the same length, and its angles have the same measure, we have that the measure of one interior angle is given by the formula
The answer is 13/40 or .325
Answer:
663 I thank
Step-by-step explanation:
12+240-8=232-360+2=362+300=663
5x60=300
6x60=360
240-8=232
4x60=240
Given:
The diagram.
To find:
(a)
(b)
(c)
Solution:
(a)
If two lines intersect each other at a point, then the vertically opposite angles are equal.
(Vertically opposite angles)
Therefore, the measure of angle SQT is 36 degrees.
(b)
If a transversal line intersect two parallel lines, then the alternate interior angles are equal.
(Alternate interior angles)
Therefore, the measure of angle QRW is 36 degrees.
(c)
It is given that the angles PRV and angle PRQ are congruent.
Let the measures of angle PRV and angle PRQ are x degrees.
(Adjacent interior angles are supplementary)
Divide both sides by 2.
Therefore, the measure of angle PRV is 72 degrees.
