Answer:
Sum = 2,340°
Step-by-step explanation:
Sum of interior angles = 180·(n-2),
where n is the number of sides the polygon has
Sum = 180·(15-2)
Sum = 180·13
Sum = 2,340°

Answer: D. 3.2
Step-by-step explanation:
Given : In parallelogram LMNO,
LM = 4.12, MN = 4, LN = 5, and OM = 6.4.
Diagonals and intersect at point R.
We know that diagonals of a parallelogram bisect each other.
Since R is the intersection point of both diagonals.
⇒R is the mid point of OM.
Thus OR=
Therefore, OR=3.2
Algebraic expression: 4n + 8 = 5
