Answer:
The complement is 53 and the supplement is 143
Step-by-step explanation:
Two complementary angles add to 90
PQR and x = 90
37+x = 90
Subtract 37 from each side
37-37 +x =90-37
x = 53
The complement is 53
Two supplementary angles add to 180 degrees
PQR and x = 180
37+x = 180
Subtract 37 from each side
37-37 +x= 180-37
x = 143
The supplement is 143

We have a dilemma here, there is a variable and constant numbers in this equation. No fear, this is when like terms comes into play, where you can only combine two numbers that have the same ending, whether it be variables, exponents, e.t.c.
Distribute :
4 + 16 - 12(1 + 2x)
4 + 16 - (12(1) + 12(2x))
4 + 16 - 12 + 24x
Use PEMDAS (Add left to right) :
4 + 16 - 12 + 24x
20 - 12 + 24x
8 + 24x
24x + 8
