Calculate the slope from the following two coordinates:
(-4,-5) and (-3,-2)

Well, find the change in y over change in x. You get three.over one. So your slope Is positive 3.

easy math just plug in a and b

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
