The interior angle of a regular polygon is twice the exterior angle how many sides has the polygon

Mathematics
1 answer:
just olya [345]2 years ago
6 0

Answer:

6 sides

Step-by-step explanation:

the interior angle + the exterior angle = 180°

let x be the exterior angle then 2x is the interior angle and

x + 2x = 180

3x = 180 ( divide both sides by 3 )

x = 60

the exterior angle = 60°

the sum of the exterior angles of a polygon = 360°

since the polygon is regular the the exterior angles are congruent, then

number of sides = 360° ÷ 60° = 6

Which quadratic rule represents the data in the table?
NeX [460]
Since there are already choices in the question, I suggest you just substitute in the values of x to each choice and check whether the corresponding value for y appears. This is also called the trial and error method in multiple choice.

The answer that represents the data in the table is C. <span>y = x^2 – 5.</span>
