Answer:
The statement is false. Exterior angles are the angles created when the sides of the triangle are extended
Step-by-step explanation:
In order to find the exterior angle of a polygon, the side of the polygon is extended to go past the vertex of the polygon to form an angle adjacent and supplementary to the the interior angle of the polygon at the vertex of the polygon where the exterior angle is formed.
The sum of the exterior angle and the adjacent interior angle is equal to 180°
The exterior angle can also be described as being formed by one side of a polygon and an extension of the adjacent side to previous side of the same polygon and it can also be referred to as a turning or an external angle.
Answer:
is the solution to the equation: 
The statement is true.
Option A is correct.
Step-by-step explanation:
We need to determine if 
is the solution to the equation:
Solving the equation first to find value of x
Combining like terms:
Subtracting 2x on both sides
Now, subtracting 12 on both sides
Divide both sides by -6
So, we get
Therefore we can say that is the solution to the equation:
The statement is true.
Option A is correct.
Two solutions were found :
u ≥ 2
u ≤ 0
Answer is a1 = 7
Using equation (derived from formula to find sum of values in a geometric series),
Hence, solve for a.
