A group of 120 students were asked how old they were when they lost their first tooth. 50% said they were 7 years old. How many students said they were 7 years old when they lost their first tooth? Explain. To find 25% of a number, divide the number by

60 cuz why not?

Step-by-step explanation:

< 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
