A regular convex polygon has eight sides. What is the measure of an exterior angle?
2 answers:
<u>Answer:</u>
Exterior angle = 45°
<u>Step-by-step explanation:</u>
We know that the sum of exterior angles of a polygon is 360 degrees.
Since here we a regular polygon with eight sides (which makes it an octagon) so this means that the interior angles each would be equal to:
= 135 degrees
We know that each interior angle is supplementary to the exterior angle at the vertex.
So each exterior angle =
= 45 degrees
Answer:
The measure of one exterior angle is 45 degrees.
Step-by-step explanation:
The formula to find exterior angle of and shape is 360 degrees divided by n (number of sides the shape has). 360 divided by 8 = 45 degrees.

The formula for the volume of a cone, V, is:
V = [1/3] * π * (radius)^2 * height
Here radius = 6 feet / 2 = 3 feet
Height = 15 feet
V = [1/3] π (3 feet)^2 * 15 feet = 45π feet^3
Answer: 45π feet^3
The answer is, y = -1/3 - 3
8:10= 0,8
0,8 or 4/5
