Write an equation of the line perpendicular to y=-3x - 5 and passes through (6,-4). y+4=?(x-6)
What
should be in the ?

all teachers

step-by-step explanation:

each side has a different length.  

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
