210 degrees for the reflex 150 degrees for the obtuse
a reflex angle is greater than 180o but it is less than 360o.
270 degrees
A polygon (with more than 3 sides) can have an angle of any measure between 0 and 360 degrees. If it is a reflex angle, it cannot have a supplement. Even if a supplementary angle exists, its size is indeterminate.
The number of memory between 12 and 1 is 5. There are 60 lines in a clock: 5/60. Since the whole angle of the clock is 360, you multiply 360 and 5/60 together and get the answer of 30 degrees.

Technically 364.999 to the Nth degree, since the hands of a clock go in circles, you could view them barely touching as an obtuse angle.

60 degree reflex? Possibly you mean 300 degrees...
the angle size is 90 degrees

acute angle = less than 90o & greater than 0o right angle = 90o obtuse angle = greater than 90o & less than 180o straight angle = 180o reflex angle = greater than 180o
The inscribed angle forms the apex of the angle. It is a point. To circumscribe the point is 360 degrees. So the inscribed angle and the reflex (outscribed) angle sum to a total of 360 degrees.
Any angular size between 0 and 90 degrees. An OBTUSE angle is one whose size is between 90 & 180 degrees. A REFLEX angle is one whose angle is between 180 & 360 degrees. NB To correct your English grammar . The question should read ' What size is an acute angle'. When the noun following the indefinite article 'a', begins with a vowel 'a,e,i,o,u'. then the indefinite article is 'an'. In this case it is 'an acute', NOT 'a acute'.
The angle between the hour hand and 1 o'clock on a clock is 30 degrees. This is because the hour hand moves 30 degrees for each hour on the clock face, and at 1 o'clock, it points directly to the 1.
