Given the proportion 8/5 = 2/m-3 what is the value of m

Hey there! :)

m = 4.25, or 17/4.

Step-by-step explanation:

Given the proportion:

Cross multiply:

8(m - 3) = 5 · 2

Distribute the 8:

8m - 8(3) = 10

8m - 24 = 10

Add 24 to both sides:

8m = 34

Divide both sides by 8:

8m/8 = 34/8

m = 4.25, or 17/4.

< 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
