Answer:

B, D

Step-by-step explanation:

Angles 1 and 2 combined form a right angle, so the sum of their measures is 90°. Therefore, they are complementary angles.

Since they share a common side and vertex and don't overlap, they are also adjacent angles.

Marina CMI [18]

Answer:

#5 :16.38

Step-by-step explanation:

perimeter:

length AB = 6-0 = 6

length BC = $\sqrt{(-1-3)^{2} + (2-6)^{2} }$ = 5.65685

length AC = $\sqrt{(-1-3)^{2} + (2-0)^{2} }$ = 4.4721
