Question

Find the sum of the measure of the interior angles of the polygon below.

image of a seven-sided polygon where all of the interior angles are acute


900°


1260°


1080°


1620°

Answer 1

Its the third choice

Step-by-step explanation:

Answer 2

The correct answer is: 900°

Step-by-step explanation:

As it is mentioned in the question that the figure (attached) has seven-sided polygon (n=7), we can find the sum of interior angles of that polygon as follows:

Sum of interior angles = (n-2) * 180° --- (A)

Where, n=7 (as mentioned above); plug in the value of n in (A):

Sum of interior angles = (7-2) * 180°

Sum of interior angles = 900°

Hence, the sum of interior angles is 900° (Option A).
