C&A Museum has three million visitors per year. Each visitor spends an averageof 1 hour in the museum. What is the average number of visitors in the museum on agiven day if the museum is open 300 days a year from 9 a. m. to 5 p. m.?

1250 visitors per day

Step-by-step explanation:

Number of visitors per year = 3,000,000

Number of days open per year = 300

Number of hours = 9a.m to 5pm = 8 hours

Number of visitors per hour :

Number of visitors per year / (number of days per year * number of hours per day)

3000000 / (300 * 8)

3000000 / 2400

= 1250 visitors per day

< 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
