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
I wanna say 14%, just because if you add the total of pieces divided by the 5 yellow with 4 holes, you'll receive the answer 0.14.
The answer is A hope this helps!
2.8
-14x+28=-4x
10x=28
X=2.8
Mark brainliest please
