Aaron is making a go-cart. aaron has 200 centimeters of steel pipe to make an axle for his cart. the axle only needs to be 150 centimeters long. how many meters of steel pipe should be cut off to make the axle?

< 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
