Answer:

x = 50

Step-by-step explanation:

In a parallelogram, consecutive angles are supplementary, thus

∠ A + ∠ B = 180 , substitute values

2x + 2x - 20 = 180

4x - 20 = 180 ( add 20 to both sides )

4x = 200 ( divide both sides by 4 )

x = 50

Alex purchased a new car for $28000. The car depreciates 7.25% each year. what will the price be in 5 years?

dalvyx [7]

Use the depreciation formula.

$\sf p(1-r)^n$

Where 'p' is the principal value, 'r' is the rate it depreciates, and 'n' is the time. Just plug in what we know:

$\sf 28000(1-0.0725)^5$

Simplify by subtracting:

$\sf 28000(0.9275)^5$

Simplify the exponent:

$\sf 28000(0.6864)$

Multiply:

$\sf\approx\boxed{\sf\$ 19219.20}$
