Jim washes 2/3 of his car with 1/2 a bottle of soap. What fraction of the soap will he use to clean his entire car?​

if he uses 1/2 for 2/3, then you can divide 2/3 and 1.2 by 2 to get the remaining soap needed to complete the wash

so to clean the last 1/3 of the car, he`ll use 1/4 of the remaining soap

the entire car needs 3/4 of a bottle of soap

Based in attached the picture, we can easily be determined the other values of the other arc in the given.
Such as enumerated below:
arc TBD= 90° +90° =180°
arc BTC= 90°+ 128° =218°
arc TCB = 128° + 52 °+90°=270°

Therefore, the answer is 270° and it is the letter "C".
