A string of decorative lights is 23 feet long. The first light on the string is 16 inches from the plug. The lights on the string are spaced 4 inches apart. How many lights are there on the string?

There are total lights on the string.

< 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
