Answer:

  see below

Step-by-step explanation:

Any line between two points on the circle is a chord.

Any angle with sides that are chords and with a vertex on the circle is an inscribed angle.

Any angle with sides that are radii and a vertex at the center of the circle is a central angle. Each central angle listed here should be considered a listing of two angles: the angle measured counterclockwise from the first radius and the angle measured clockwise from the first radius.

<h3>1.</h3>

chords: DE, EF

inscribed angles: DEF

central angles: DCF . . . . . note that C is always the vertex of a central angle

<h3>2.</h3>

chords: RS, RT, ST, SU

inscribed angles: SRT, RSU, RST, RTS, TSU

central angles: RCS, RCT, RCU, SCT, SCU, TCU

<h3>3.</h3>

chords: DF, DG, EF, EG

inscribed angles: FDG, FEG, DFE, DGE

central angles: none

<h3>4.</h3>

chords: AE

inscribed angles: none

central angles: ACB, ACD, ACE, BCD, BCE, DCE

PLS I NEED HELP! Which graph grows the fastest as x gets larger?
jok3333 [9.3K]

Answer:

y=5^x

Step-by-step explanation:

5 to whatever power will always be larger than 4, 3, or 2.

For example:

3 squared = 9

5 squared = 25

4 squared = 16

2 squared = 4

25 is greater than 9, 16, and 4

Theoretically, if a month is chosen 300 times,
horsena [70]

Answer:

75 times.

Step-by-step explanation:

Well there are 12 months and 3 of them start with the letter J, so theoretically, 25% of the months chosen will start with the letter J because \frac{3}{12}=\frac{1}{4}, which is 25%. 25% of 300 (or \frac{300}{4}, for those who like fractions) is 75, so theoretically, we can expect a month that starts with the letter J 75 times.

Hope this helps!

Could someone please help me figure out how to set up the equation for this problem? Thanks!
faust18 [17]

Answer:

12

Step-by-step explanation:


The sum of the measures of the interior angles is given by:


(n-2)*180\\


n:sides of the polygon


And in a convex polygon the sum of the exterior angles sums 360°


Then


(n-2)*180=5*(360)


You just solve it and the answer is 12.
