In the diagram below angle AED=(4n-20)° and angle BEC=(2n-16)°. What is the measure of angle CED in degrees
Pavlova-9 [17]

Check the picture below.

so, bearing in mind that vertical angles are equal, thus ∡AED = ∡BEC, and we know that ∡BEC = 52 = ∡AED, so those two angles added up are 104°.

now, a circle has a total of 360°, if we take away those 104° from the red angles, what's leftover is just 256°, well, the green angles there are also vertical angles and thus twins, so each one will take half of 256°.

∡BEA = 128° = ∡CED.

How much interest would $2,000 earn, with simple interest, in two years at the<br>rate of 4.2%?​
Anna [14]

Answer:

$168

Step-by-step explanation:

The formula we'll use for this is the simple interest formula, or:

I=Prt

Where:

P is the principal amount, $2000.00.

r is the interest rate, 4.2% per year, or in decimal form, 4.2/100=0.042.

t is the time involved, 2....year(s) time periods.

So, t is 2....year time periods.

To find the simple interest, we multiply 2000 × 0.042 × 2 to get that:

The interest is: $168.00

Solve step by step<br>2(p+8)=26
romanna [79]

Answer:

<h2>p = 5</h2>

Step-by-step explanation:

2(p+8)=26\qquad\text{divide both sides by 2}\\\\\dfrac{2\!\!\!\!\diagup^1(p+8)}{2\!\!\!\!\diagup_1}=\dfrac{26\!\!\!\!\!\diagup^{13}}{2\!\!\!\!\diagup_1}\\\\p+8=13\qquad\text{subtract 8 from both sides}\\\\p=5
