Your payment is $350 per month for 48 months and you made a 3,000 down payment?

Your total cost would be $19800

Step-by-step explanation:

350*48

=16800

+3000

=19800

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

thats not a system of equations, that is a solution
