Angle 3 and angle 1 are vertical angles. This means that they are equal to each other. Since angle 3 is 111 degrees that means that angle 1 is also 111 degrees

Angle 2 is adjacent to angle 3. This means that their sum is 180 degrees. With this knowledge you can make a formula like so (let angle 2 be x):

111 + x = 180

x = 69

Angle 2 is 69 degrees

Angle 4 and angle 2 are adjacent. Again, this means that they are equal to each other. Angle 4 is 69 degrees

Hope this helped!

Angle 1 and 3 are vertical angles, which mean they are identical. Since angle 3 is given as 111 degrees, then angle 1 is also 111 degrees.

All four angles need to equal 360.

Subtract angle 1 and 3 from 360:

360 - 111 - 111 = 138

Angle 2 and 4 would also be identical, so divide the 138 by 2:

138 / 2 = 69

Angle 2 and angle 4 are both 69 degrees.

Stella [2.4K]

Answer:

Anything that does not cost more than $2,560.00

Step-by-step explanation:

Provided that Nikita is spending money that she had invested and the amount  she collected over the period of 7 years. She can buy any item that costs no more than $2,560.00 but how?

It is a problem of simple interest:

Here the principal amount (P) = $2,000.00

Interest rate (r) = 4%

Time period (t) = 7 years

So, total amount that she would get by the end of 7 years is:

A=P+SI

SI=\frac{P\times r\times t}{100}

Plugging the values we get:

SI=\frac{2000\times 4\times 7}{100}=560.00

So the interest collected over 7 years is $560.00

Therefore, the total amount after 7 years is:

\$2000.00+\$560.00=\$2,560.00

If Nikita is using this money then the most expensive item that she could buy will cost no more than $2,560.00.

Sara's results probably do have a higher mean, if we take into account how William is way more willing to pay 20 dollars. Honestly, I think you got your chosen answers right! Just my opinion, as someone inexperienced.
