Answer:

114.59\°

Step-by-step explanation:

we know that

The circumference of a circle is equal to

C=2\pi r

In this problem we have

r=3\ cm

substitute

C=2\pi (3)=6 \pi\ cm

Remember that

360\° subtends the arc length of the complete circle

so

by proportion

Find the measure of the central angle for an arc length of 6\ cm

\frac{360}{6\pi } \frac{degrees}{cm} =\frac{x}{6} \frac{degrees}{cm} \\ \\x=6*360/(6\pi )\\\\ x=114.59\°

Help pls<br> What is the value of RS?
andreyandreev [35.5K]

Answer:

RS = 16

Step-by-step explanation:

If a line is parallel to a side of a triangle and intersects the other 2 sides , it divides those sides proportionally.

PR is such a line , then

\frac{QR}{RS} = \frac{QP}{PT} ( substitute values )

\frac{32}{RS} = \frac{42}{21} = 2 ( multiply both sides by RS )

32 = 2 RS ( divide both sides by 2 )

16 = RS

Simplify the expression:<br> –9w+–6w+10w+8w
Y_Kistochka [10]

Final Answer: 3w

Steps/Reasons/Explanation:

It is common addition and subtraction because they all have w after the number. This means they are the same variable. A plus minus (+-) would be a minus (-).

Question: Simplify the expression: -9w +- 6w + 10w + 8w.

<u>Step 1</u>: Simplify.

-9w - 6w + 10w + 8w

<u>Step 2</u>: Simplify.

3w
