10 rays can meet in 45 vertices. At each such vertex there will be 4 angles which makes 180 angles in all.

How many angles are formed by 5 noncollinear rays intersecting at a common end point?
Ten.Each angle is determined by two rays, so the answer is equivalent to the number of combinations of 2 out of 5 = 5*4/(2*1) = 10
How many perpendicular angles does a pentagonal prism have?
A pentagonal prism has 10 right angles, formed from perpendicular edges. It has one for each angle made when a face meets a base. Since it has 5 faces and 2 bases, there are 10 right angles.
How many angles does a decagon have?
A decagon has 10 angles (and sides)
How many angles does 10 squares have?
A square has 4 angles, so ten squares have 10*4 = 40 angles.
How many obtuse and acute angles in a decagon?
There can be 10 obtuse angles. If there are no reflex angles there can by up to three acute angles (I think).

Ten.Each angle is determined by two rays, so the answer is equivalent to the number of combinations of 2 out of 5 = 5*4/(2*1) = 10
How many angles are formed by 12 distinct rays with a common endpoint?
There are 66 angles formed by 12 distinct rays with a common endpoint. The first ray by itself doesn't make an angle, the second ray makes 11 distinct angles, the third ray makes 10, the fourth 9, the fifth - 8, the sixth - 7, the seventh-6, the eighth - 5, the ninth- 4, the tenth - 3, the eleventh - 2, and the twelfth - 1 (it makes an angle with the first ray).
How many angles does a pentagonal prism have?
A pentagonal prism has ten solid angles. Each of these is formed where three faces meet - so there are 3*10 = 30 dihedral angles.
What is the pattern in determining of numbers of angles form the given numbers of rays?
Number of rays subtracted by one and adding all previous numbers. Example : number of rays : 13 13-1=12 1+2+3+4+5+6+7+8+9+10+11+12=78 there are 78 angles in 13 rays. Or if you were given a sequence pattern. Number of rays. Number of angles. 1-0 2-1 3-3 4-6 5-10 6-? 7-? Get number of rays minus 1 then add it to the previous number of angles. 6-1=5 5 + 10 (number of angles in 5 rays) = 15 7-1=6 6 + 15 (number of angles in 6 rays) = 21 -werty-sama
How many perpendicular angles does a pentagonal prism have?
A pentagonal prism has 10 right angles, formed from perpendicular edges. It has one for each angle made when a face meets a base. Since it has 5 faces and 2 bases, there are 10 right angles.
How many angles does a star have?
10 angles
How many Decagon angles are there?
There (not their) are 10 angles.
How many angles a star have?
10 angles
How many angles and sides does a star have?
10 sides and 10 angles
How many angles would a polygon with 10 sides have?
A polygon has as many angles as sides, so a polygon with 10 sides (decagon) would have 10 angles.
How many angles does a decagon have?
A decagon has 10 angles (and sides)
How many angles does 10 squares have?
A square has 4 angles, so ten squares have 10*4 = 40 angles.
