David puts 0 . 40.4 liters of solution in each of 55 beakers. ​

​ How much solution is there in total?

2 liters

Step-by-step explanation:

There are 5 beakers in total, in which David adds 0.4 liters into each of them. To solve, multiply 5 with 0.4: 5 x 0.4 = 2.0 2.0 or 2 liters is your answer.

2.0 or 2 liters is your answer.

< 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
