Find the distance between the points L(7,-1) and MC (– 2, 4). The exact distance between the two points is

d= 10.30

Step-by-step explanation:

Using distance formula:

d=√(-2-7)² + (4--1)²

d=√(-9)² + (5)²

d=√81 + 25

d=√106

d≈ 10.296

< 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
