When you have parallel lines same side interior angles add up to 180 degrees.
Let the first SSI (same side interior) angle be x, and the other SSI be (x - 20).
Therefore, x + (x - 20) = 180
2x - 20 = 180
add 20  to both side
2x = 200
divide both sides by 2
x = 100
x - 20 =  100 - 20 = 80

Contact [7]

a) The amount Sandy will pay for the dishwasher that costs R6,500 today on hire purchase is <u>R7,772.04</u>.

b) The monthly repayments are <u>R215.89</u>.

c) The total interest paid is  R1,272.04.​

<h3>What is a hire purchase?</h3>

Hire purchase is a credit agreement that allows the buyer to make monthly payments in consideration of finance charges.

The total amount the buyer will pay periodically for the hire purchase is the cost (the price of the item) plus the total interest (finance charge).

These can be determined using an online finance calculator as follows:

<h3>Data and Calculations:</h3>

Cost of dishwasher = R6,500

Hire purchase terms = 3 years equal monthly payments

Interest rate = 12%

N (# of periods) = 36 months ( 3 x 12)

I/Y (Interest per year) = 12%

PV (Present Value) = R6500

FV (Future Value) = R0

<u>Results</u>:

Monthly payment = R215.89

Sum of all periodic payments = R7,772.04 (R215.89 x 36)

Total Interest = R1,272.04 (R7,772.04 - R6,500)
