Apony keg (quarter barrel) of beer contains 62 pints. if the local drinking establishment sells draft beer in 400ml pilsner glasses, how many pilsners are in each pony keg?

1 pint = 473.176 milliliters

62 x 473.176 = 215336.912 milliliters in a pony keg

215336.912/400 = 538.34 glasses

 round off answer to 538 glasses

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

< 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
