Question
If the sum of 
angles in a hexagon is equal to 
, what is the value of the remaining sixth angle?
If the sum of
Answer
The sum of the angles in a polygon can be found using the equation below, in which t is equal to the total sum of the angles, and n is equal to the number of sides.
Given that a hexagon has 6 angles, the total number of angles will be:
Given that 5 of the angles have a sum of 650 degrees, we would subtract 650 from 720, resulting in 70 degrees.
