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
