What is the value of a? enter your answer in the box. a = a right triangle with base labeled as 20. the hypotenuse is labeled as 25. the perpendicular is labeled as a. the angle made between the base and the perpendicular is marked as a right angle.

15 according to the test

Step-by-step explanation:

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.
