I don't understand Which of the following expressions is equal to m4? A. m + m + m + m

B. m/4

c. m · m · m · m

D, m · 4

C

Step-by-step explanation:

If it’s m^4 it would be c since an exponent means you multiply the m by itself 4 times.

< 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
