Find the slope of the line that passes through the given points (2,-7), (1,4)

Slope “m” = 1

Hence, the slope of the required line is 1.

Step-by-step explanation:

7/2+ -4/1 = 3/3 which is a whole number

< 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
