Question

The measure of a single interior angle in a regular octagon is (4x + 12)0. Find the value of x, rounding your answer to the nearest tenth. .

Answer 1

Step-by-step explanation:

The sum of the internal angles of a polygon of N sides is

(180)*(N-2) degrees.

For N = 8 (any octagon), the total is 6*180 = 1080 degrees, and in a regular octagon, each angle is 1/8 of that or 135 degrees.

Set 4x + 12 equal to 135 and solve for x. The answer will not be an integer

Hope this helps

Answer 2

Answer:

135

Step-by-step explanation:

What is the measure of each angle in a regular octagon? Explanation: An octagon contains six triangles, or 1080 degrees. This means with 8 angles, each angle is 135 degrees.
