Answer:
A fruit seller buys some oranges and by selling 40% of them he realizes the cost price of all the oranges. As the oranges being to grow over-ripe, he reduces the price and sells 80% of the remaining oranges at half the previous rate of profit.
Step-by-step explanation:
169
Surface area (SA) = 2B + PH
SA = 2 ( x 9 x 6) + (7+7+9) 5
= 2 (27) + (23) 5
= 54 + 115
SA = 169
X+20° = 180°
or, X = 180°-20°
or, X = 160°
it's (6,0) I can't explain though
x > 16
