Answer fast pls thanks

< 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

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

(a)   the cost of the fruit in $2 per lb = slope of the line

a cost of $10 ( the height of the vertical axis) and a weight of the strawberries ( the corresponding point on x axis)

so the lope   is   10/5 = 2   that is $2 per lb of strawberries

cost = 2w   where   w = weight of strawberries in pounds

(b) in the same   way cost of each lb of   blueberries = 10/7 =   $ 1.43

cost =   10w/7     where w = weight of blueberries in lbs.

c)     blueberries are cheaper ( $1.43 / lb against   %1 per lb for strawberries)

i tried my best if i'm right if i'm wrong i am so sorry.but if i am right plzzz mark brainliest: )
