A road sign is in the shape of a regular heptagon. What is the measure of each angle on the sign? round to the nearest 10th.
a. 128.6 degrees ***
b. 900 degrees
c. 64.3 degrees
d. 231.4 degrees
correct
128.6 degrees is the answer my good sir
Yup it’s right
128.6 would be your answer!
To determine the measure of each angle on a regular heptagon, you need to divide the total sum of the interior angles by the number of angles (in this case, 7).
The formula to find the sum of the interior angles of a polygon is (n-2) * 180, where n represents the number of sides.
For a heptagon, the sum of the interior angles is (7-2) * 180 = 5 * 180 = 900 degrees.
To find the measure of each angle, divide the sum by the number of angles: 900 / 7 = 128.6 degrees (rounded to the nearest 10th).
Therefore, the correct answer is a. 128.6 degrees.
