The ratio of boys to girls in a certain school is 2:3 calculate how many boys are there if there are 1500 learners in the school.​

700

Step-by-step explanation:

the answer is 900 students

Step-by-step explanation:

if there are 5 parts to the ratio then take that and divide it by the total number of learners and then multply it by the ratio for the boys

< 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
