M∠DAB + m∠ABC = 180°

m∠DAB + 72° = 180°

Subtract 72° on both sides.

m∠DAB = 180° - 72°

m∠DAB = 108°


Your final answer is B. 108°

You decide to buy a 60 in plasma-screen tv. you borrow $4300 from the electronics store at 1.8% per month simple interest, with
const2013 [10]

4300 is your principal

1.8% interest rate (change it into decimal form; 0.018)

2 years is our time

We'll now multiply our variables.

4300 x 0.018 x 2 = 154.80

This shows that in 2 years at their interest rate that they have earned 154.80.

We will add the $154.80 to the original borrowed amount of 4300.

$4454.80 will be how much they will owe after 2 years.


To find out the amount in 15 months we'll divide 15 months by 12 and we get 1.25 and now we multiply the numbers again.

4300 x 0.018 x 1.25 = 96.75

They will pay $96.75 in interest within 15 months and we'll add it to the 4300.

$4397 will be how much they will pay after 15 months.
