An angle measures 12° more than the measure of its complementary angle. What is the measure of each angle?

The angles are 39 and 51

Step-by-step explanation:

Let x be the unknown angle

x+12 is the complement

Complements add to 90

x+x+12 = 90

Combine like terms

2x+12 = 90

Subtract 12 from each side

2x+12-12 = 90-12

2x = 78

Divide by 2

2x/2 = 78/2

x =39

x+12 = 39+12

         =51

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.
