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°

The correct answer is: 900°

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).

Its the third choice

Step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
