Place value? Scientific notation? Exponents?
The correct answer is (-7/2,-1/2) or (-3.5,-0.5) To find the midpoint of a segment, add both "x" coordinates, divide by 2. Then add both "y" coordinates, and divide by 2
Answer:
The correct answer is D. 360°
Step-by-step explanation:
The sum of all the exterior angles of a regular n-gon or a polygon is always equal to 360°.
Let us consider the image attached.
First of all let us consider the triangle.
As per the property of exterior angles: The exterior angle is equal to the sum of 2 opposite interior angles.
Where are the interior angles of the triangle.
Adding the above equations:
The sum of interior angles of a triangle is always equal to 180°
Hence, proved that the sum of exterior angles is .
So, the correct answer is D.
