An aquarium holds 780 gallons of water. A pump can drain the tank at a rate of 24 gallons per hour. The correct equation is w = 780 - 24h
What is the rate?

Answer

78894-Qm 4443-232

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
