Answer:
a) 126degrees
b) 47degrees
Step-by-step explanation:
The sum of two supplementary angles is 180 degrees.
Let the other angle be x
x + 54 = 180
x = 180 - 54
x = 126degrees
The supplement is 126degrees
b) The sum of two complementary angles is 90 degrees.
Let the other angle be y
y + 43 = 90
y = 90 - 43
y = 47degrees
Hence the complement is 47 degrees
