The sum of the measures of angles x and y is 120°. The measure of the angle x is 12 less than the measure of the angle y.

Maru [420]

Answer:

Y-12 + y =120 take 12 to the other side get 2 y = 132

Y=66 so y-12=x

X=54

If the balance at the end of eight years on an investment of $630 that has been invested at a rate of 9% is $1,083.60, how much

Contact [7]

The interest is $453.60.

The total amount includes principal + interest. The principal was 630 and the total amount was 1083.60.
1083.60 - 630 = 453.60.

IF NR = 8 ft, what is the length of arc NMP. Round to the nearest tenth.

Pavlova-9 [17]

Check the picture below.

since chords NQ and MP cross the center of the circle at R, that means that those two chords are diametrical chords and the angles made by both are vertical angles and thus twin angles, namely both are 18° as you see in the picture, so the angle NMP in magenta is really 162° + 18° + 18° = 198°, and we know the radius NR is 8.

$\textit{arc's length}\\\\ s=\cfrac{r\pi \theta }{180}~~ \begin{cases} r=radius\\ \theta =\stackrel{degrees}{angle}\\[-0.5em] \hrulefill\\ r=8\\ \theta =198 \end{cases}\implies s=\cfrac{(8)\pi (198)}{180}\implies s\approx 27.6$
