Use the inscribed angle rule to find the value of xin each circle. Show your work.
denis23 [38]

Answer:

Left: x = 56

Right: x = 58 1/2

Step-by-step explanation:

The <em>inscribed angle theorem </em>says that the inscribed angle subtended by an arc is half the measure of the central angle subtended by that same arc. In other words, if we had an arc with a measure of 12 degrees, its corresponding inscribed angle would be exactly 6 degrees, and if we had an inscribed angle measuring 10 degrees, it would be subtend an arc measuring 20 degrees.

On the left, we're given a measure of 28 degrees for the inscribed angle and have to find the measure of x, the subtended arc. Since 28 has to be half of x by the inscribed angle theorem, x must be 28 x 2 = 56°

On the right, we're given an arc with a measure of 117°, and we have to find the measure x° of the inscribed angle. Of course, this angle must be half of 117, so x = 117/2 = 58 1/2.

Find the number of years it would take for $1200 to earn simple interest of $324 at an annual interest rate of 6% per year
topjm [15]

ANSWER

It would take 45 good years

<u>EXPLANATION</u>

We calculate simple interest using the formula,

I=\frac{P\times T\times R}{100}


From the question,


I=324 dollars


R=6%

and

P=120 dollars


We substitute into the above formula

324=\frac{120\times T\times 6}{100}


324=\frac{720\times T}{100}

324\times100=720\times T


\frac{324\times100}{720}=T



\frac{324\times10}{72}=T


45=T


Therefore it would take 45 years.
