Let

S------> The sum of the measures of the interior angles of a polygon

n-------> number of sides of a polygon

we know that

The formula to find the sum of the measures of the interior angles of a polygon is equal to

S=(n-2)*180°

in this problem

S=2880°

Solve for n

S=(n-2)*180\\ \\ n=\frac{S}{180}+2\\ \\ n=\frac{2880}{180}+2\\ \\ n=16+2\\ \\ n=18\ sides

therefore

the answer is

18\ sides

The following quadrilateral is a trapezoid. What is the measurement of the angle J?
GarryVolchara [31]

Answer:

65

Step-by-step explanation:

A trapezoid means that the lines are parallel, meaning that angle K + angle J = 180. So angle J = 180 = 115 = 65
