Help me with 21 and 22

21) m<1 = 122

22) m<2 = 58

Step-by-step explanation:

21)

m<1 = 122

because they are vertical angles which means they're equal to each other

22)

m<2 + 122 = 180 (because they're supplementary angles)

m<2 = 180 - 122

m<2 = 58

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.

i would need to see the dot plot : )
