I need help with all four Identify the cords, inscribed angles, and central angles in the figure. The center of the circles in #1,2, and 4 is C.

Answers

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.

1.

chords: DE, EF

inscribed angles: DEF

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

2.

chords: RS, RT, ST, SU

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

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

3.

chords: DF, DG, EF, EG

inscribed angles: FDG, FEG, DFE, DGE

central angles: none

4.

chords: AE

inscribed angles: none

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

Answers

Answer: 3.65

Step-by-step explanation:

This question is asking basically what is 50% or 1/2 of 7.3.

Let's expand the number 7.3

Then, we end up getting 7.30.

We have to find 1/2 of 7.30.

$(1)/(2)$ of 7.30 = $3.65$

The sum of two intcgers is -6. If one of them is 2, then the other is(a) 4
(b) 4
(c) 8
(d) -8

Answers

Answer:

D) -8

Step-by-step explanation:

If you add a positive and a negative, you end up subtracting. If your sum is lower than any of the numbers you are adding together, then there is a negative. In this case, your only negative number is -8, but if there were others, you could find this equation by doing negative six minus two (because the equation was originally addition, it would still be subtraction to check your work or find the answer in this case.)

Hopefully you find this useful :)

Answer: -8

Step-by-step explanation: lets take the unknown number as x,

so we have, 2 + x= -6

by using transposition method, x= -6-2( positive becomes

negative when transpositioning)

so, x= -8
