Question

(3) Find the sum of all interior angles of a 12 sided regular polygon.​

Answer 1

Answer:

1800

Step-by-step explanation:

The formula for sum of interior angles of polygon = (n-2)* 180

where, n = no. of sides

Sum of interior angles of 12 sided regular polygon = (12-2)*180 = 10*180= 1800

Answer 2

Given,

Number of sides of the regular polygon, $\[n = 12\]$

Solution,

Know that the sum of interior angle of n- sided polygon is $\[\left( {n - 2} \right)180^\circ \]$

$\[\begin{array}{l} = \left( {n - 2} \right)180^\circ \\ = \left( {12 - 2} \right)180^\circ \\ = 10 \times 180^\circ \\ = 1800^\circ \end{array}\]$

Hence the sum of interior angle is $\[1800^\circ \]$
