Answer:

20

Step-by-step explanation:

3x + 4x - 15

3(5)+4(5) - 15

15 + 20 - 15

You can add the oposites

15 + (-15)

= 0

And then you have 20 left. Or add 15 + 20 = 35 then subtract 15 (which equals 20)

Hope this helps!

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
