Penguins at the zoo are fed two times a day. A colony of penguins ate a total of 417 fish yesterday. During their morning feeding they ate 156 fish. After a few hours of swimming, they were hungry again and ready for their afternoon feeding. How many fish did the colony of penguins eat in their afternoon feeding?

The colony of penguins eat 261 fish in their afternoon

Step-by-step explanation:

To carry out this problem we simply have to subtract the amount of fish that were eaten in the morning from the total

t = total = 417 fish

m = morning = 156 fish

a = afternoon

a = t - m

a = 417 - 156

a = 261

The colony of penguins eat 261 fish in their afternoon

< 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
