I saw this same type of question and page but with different numbers just 5 minutes ago...
Anyway here’s the answers:
1) Complementary
3x+1+44=90
3x+45=90
3x=45
x=5
2) Vertical
Ignore everything about the work. The answer is 120 degrees because they’re vertical angles.
3) Supplementary
15x-5+110=180
15x+105=180
15x=75
x=5
And I can’t see the last question clearly
0.46666666666666. its a repeating decimal. or you could write it as 0.47.
The answer should be 18.75 pounds
multiply 5(amount bought) by 3 3/4(how much each one weighs)
