Interior angle = 3 x exterior angle.
Hence Int Ang + Ext Ang = 180
Substituting
3 x Ext + Ext = 180
4 Ext = 180
Ext Angle = 180 / 4 = 45 degrees.
And
Exterior Ang;e = 360 / number of sides.
number of sides = 360/ exterior angle
No. of sides = 360/45 = 8
Hence the number of sides of the polygon is '8' . It is named as an OCTAGON.
It is a regular 8 sided octagon whose interior angles are 135 degrees and its exterior angles are 45 degrees

The lines of the treble clef, from bottom to top: EGBDF. The spaces from bottom to top are FACE.(FACE is an actual word, so it's easy to remember; the mnemonic for the lines is Every Good Boy Does Fine.)The lines of the bass clef, from bottom to top, are GBDFA. The spaces (bottom to top) are ACEG.(The mnemonic for the lines is Good Boys Do Fine Always; I'm not aware of a mnemonic for the spaces, but it's pretty easy to figure out.)
Oh, dude, you're looking for the next term in the sequence after double, triple, and quadruple? That would be quintuple! It's like when you order a burger and ask for extra cheese, and they give you quintuple cheese - because who doesn't want that much cheese, am I right?

same way u read regular music
Instruments don't play in clefs--people do. In the orchestral world, we trombonists are expected to play in Treble, Alto, Tenor, & Bass clefs on a regular basis. Jazz world is mostly Treble & Bass, though occassionally I've seen Tenor there as well.
The octave treble clef is significant in music notation because it indicates that the notes written on the staff are one octave higher than they would be with a regular treble clef. This allows musicians to read and play music that spans a wider range of pitches.
Treble is the highest. Bass is lowest, then alto, then treble.
a treble cleff is a number
Treble
Please increase the treble. I've got a treble hook caught in my left ear.
Bass is low, treble is high.
The treble clef.
