Show work plz hahaha

you borrow money for a new car from the bank. after month 1, the loan balance is $14,760. after month 2, it is $14,520. if this pattern continues, what will the balance be after 21 months?

The balance after 21 months is  $9960.

Let a₁ = 14760, a₂ = 14520, and a₂₁ be the balance after 21 months:

So we apply the given values to get the missing values:

First, we get the common difference, That is,

d = a₂ - a₁

d = 14520 - 14760

d = -240

So, we substitute the value of common difference and the known values,

a₂₁ = a₁ + (n-1)d

a₂₁ = 14760 + (21-1)(-240) 

a₂₁ = 14760 + (20)(-240) 

a₂₁ = 14760+(-4800)

a₂₁ = 9960

Therefore, the balance after 21 months is  $9960.

(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

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
