8. A right triangle has an angle measure of 52.40. What is the
value of x, the missing angle?

The missing angle is 37.60 degrees.

Step-by-step explanation: 180-90-52.40=37.60

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 a i belaeve atleast thats what my calculator just gfave me
