Tracy purchased a car and is paying monthly installments of $141.70 per month to pay it off. If it takes her $30 months to pay it off, how much will she have spent on car repayments in total?

answer: i believe it’s 245.04

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
