Answer:
63 degrees and 27 degrees
Step-by-step explanation:
Complementary angles are when two angles add to 90 degrees.
So, we can check if these pairs add up to 90 degrees.
45 + 95 = 140
38 + 42 = 80
30 + 51 = 81
63 + 27 = 90
The only pair of angles that are complementary is 63 degrees and 27 degrees.
Answer:
-20 + 30x
Step-by-step explanation:
-10(1) = -10

-10 + -10 = -20
-20 + 30x
It's geometry, help him with a problem number of 28 please.
