Answer:
complement of 51 is 39
supplement of 54 is 126
Explanation:
Complementary angles add to 90 degrees
51 + c = 90
Subtract 51 from each side
51-51 + c = 90-51
c = 39
The complement is 31
Supplementary angles add to 180 degrees
54 + s = 180
Subtract 54 from each side
54-54 + s = 180-54
s = 126
The supplement is 126
