Irina18 [472]

Notice y° and y° and 50°, are all three angles in a flat-line, namely "linear angles", and since a flat-line is always 180°.

$\bf y+y+50=180\implies 2y=180-50\implies 2y=130
\\\\\\
y=\cfrac{130}{2}\implies y=65$

Please answer this question.

Nana76 [90]

Answer:

B) 14%

Step-by-step explanation:

principal = 220000

First two years 10% paid.

.10 x 220000 = 22000

220000-22000 = 198000

x = percent

x = $\frac{New -Old}{Old}$

x = $\frac{170000-198000}{198000}$

x = -.1414

Round to .14

14% is the difference in amounts.

The principal (198000) will need to be reduced 14% to equal 170000
