I'm giving Brainliest to CORRECT answers. (IF I GET AN UNKNOWN LINK I WILL DESTROY YOU) a. List all the factors of 42. b. What is the greatest common factor of 42 and 15? c. What is the greatest common factor of 42 and 50?

Step-by-step explanation:

a) 1,2,3,6,7,14,21,42

b)3

c)2

A) 1, 2, 3, 6, 7, 14, 21, 42

B) 3

C) 2

Step-by-step explanation:

< 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
