Awoman put $580 into a savings account for one year. the rate of interest on the account was 61 1/2%. how much was the interest for the year in dollars and cents? ( round to the nearest cent )

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
