BD is 31 degrees because it is the same.
ADB is 90-31 because it is a right angle ( 59 degrees)
DEC is 180 - (31*2) because the 180 is of the trangle and the 31 is the same on the other side so times 2 then removed from 180

I only know this because I remember the common fractions, and 1/3 is .3333 repeating.
To find the car's total price, add the tax paid to the car's original price.
$32800 + $1968 = $34768
The total cost is $34,768
5/6 and 3/4 don’t have the same denominator so you have to change it to 10/12 and 9/12 to get them to be equivalent then add them together and get 19/12 simplify and get 1 7/12!
