I forgot what they’re called but the angles opposite to each other are the same degree. It’s a theorem, just search up the name
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
Answer:
1/3 of 3 hours should be 20 minutes
Absolute value of -1/3 is 1/3
