Answer:
sum of the measure of the angles in a polygon with n sides is (n - 2)*180°. If the angles of a given polygon are given in terms of x, it is possible to find the value of x by using this formula. The number of sides that the polygon has is given, so first plug that value into the formula (n - 2)*180°.
Step-by-step explanation:
The value of x is 120 degree because the sum of the exterior angles in the triangle is 360 degree.
A polygon is a geometric figure with a finite number of sides in two dimensions. On the sides or edges of a polygon, straight-line segments are joined end to end to form a closed shape. The vertices, also known as corners, are the points where two line segments meet and form an angle.
We have the number of sides = 3(triangle)
We know that the sum of the exterior angles in triangle = 360 degree
Each exterior angles x = 360/3 = 120 degree
Thus, the value of x is 120 degree because the sum of the exterior angles in the triangle is 360 degree.
