You start your elevator ride on the ground floor (0). You first go up 8 floors, then down 6 floors. Next, you go up 3 floors and up 6 floors. Finally, you go up 7 floors and down 9 floors. On what floor does your ride end?

Floor nine

Step-by-step explanation:

(8 - 6 )+( 3 + 6 + 7) - 9

2 + 16 - 9

18 - 9 = 9

Floor nine

Hopefully this help you

pls mark brainlest

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
