I’m not sure is D , I’m clueless
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

<h3>Further explanation</h3>
The percent is a number that shows a comparison of the number 100 or can be called per hundred (symbol%)
Formula used:

Fractions either proper or mixed (consisting of numerators and denominators) or decimal forms
The percentage can be expressed as a decimal by moving the decimal point two places to the left
One way to convert proper fractions to percent forms is by multiplying the fraction by 100% or By changing the denominator to 100 because percent is the percent. Multiply the numerator and denominator with the same number
