-5·6 please show work

Step-by-step explanation:

-5 + -5 + -5 + -5 + -5 + -5 = -30

Is this what you meant by showing my work?

-30

Step-by-step explanation:

if there is one negative and one positive it will always be a negative answer

ex:

(-)×(+)=(-) -5×6=-30

< 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
