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
If the price of the item drops by 60% then that means the new price is 40% of the original
new price = p*0.4
ex:
new price = $100*0.4= $40
new price= $75*0.4 = $30
