Which formula gives the average rate of change of Rx) over the interval [8, 12]? OA.
f(8) – f(12)/12 – 8
B. f(12) - f(8)/8-12
OC. f(12) – f(8)/12-8
OD. f(12)-f(8)

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2

< 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
