Answer:
m∠A=30°
Step-by-step explanation:
we know that
<u><em>Vertical Angles</em></u> are the angles opposite each other when two lines cross.
Vertical angles always are congruent
In this problem
m∠A=m∠B ----> by vertical angles
we have
m∠A=x
m∠B=3x-60
substitute
Solve for x
therefore
m∠A=30°
Answer:
(A)
Step-by-step explanation:
Cost of car = $21,349
Down payment = $3000
Remaining amount left = $18,349
Monthly payments (A) = $352
n = Total periods = 5years = 5*12= 60
P(loan amount) = 18,349
r = rate of interest monthly = r/12
Using formula, A =
352 = [tex]\frac{18349\frac{r}{12} }{1-(1+\frac{r}{12})^{-60} }[/tex
= 0.059(approx)
Annual percentage rate = 5.9%
