Answer: 27.69⁰
Step-by-step explanation:
Formula for finding the internal angle of a regular polygon is
( 2n - 4 )right angle triangle or
( 2n - 4 )90°, it can also be broken down by factorizing the expression since 2 is common,
( n - 2 )180 or supplementary
Now to find the value of n which correspond to the number of sides the polygon has, we equate the formula to the angle sum of the polygon.
( n - 2 ) × 180° = 1980°
open the bracket
180n° - 360° = 1980°
180n° = 1980° + 360°
= 2340
To find n, divide by 180 which is the coefficient of n
n = ²³⁴⁰/₁₈₀
= 13
The polygon has 13, sides
To find the measure of each angle,
Recall, the sum total of external angle = 360⁰
Therefore, to find the value of each of the angles, we divide 360 by n which is 13
³⁶⁰/n
= ³⁶⁰/₁₃
= 27.69⁰
It’s 0.71 is the answer I divid
The mean is 13.4 because after I add the numbers in the set, the sum comes out to be 134. There are 10 numbers in the set, so you divide 134 by 10, which is 13.4 (134 <span>÷ 10 = 13.4). That is how you get the mean. It's "mean" to you because you 'gotta do a lot of work to get your final mean. </span>
A quadrilateral that has all congruent sides and all right angles is known as a square.
Given is a quadrilateral with all right angles and congruent sides.
<h3>What is a Quadrilateral?</h3>
A four-sided polygon having four sides and four corners is referred to as a quadrilateral in geometry .
<h3>What are Congruent sides?</h3>
Congruent sides refers to a figure's sides being equal to one another.
We know that,
A square is a quadrilateral with angles that are each 90 degrees.
Additionally, a square has four equal sides, making it a quadrilateral having all sides congruent.
As a result, a square is a quadrilateral with congruent sides and all right angles.
