Answer:
23°
Step-by-step explanation:
157° = D
D + C = 180°
157 + C = 180
(group like terms)
C = 180 - 157
C= 23°
10% of $20 is $2 (take off the end 0)
$20+10%=?
$20+$2[this is 10%]=$22
The selling price is $22
3/4 tons = 1500 lbs/pounds
Add the total purchase then subtract the used amount from it. U'll get 2 1/3.
