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
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.
A decagon has 10 angles (and sides)
A square has 4 angles, so ten squares have 10*4 = 40 angles.
There can be 10 obtuse angles. If there are no reflex angles there can by up to three acute angles (I think).

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).
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

Oh, dude, a pentagonal prism has like, a total of 10 angles. Each pentagon face has 5 angles, and then there are 5 more angles where the faces meet. So, like, if you're into angles, this shape is a real party with 10 of them hanging out.
10 angles
There (not their) are 10 angles.
10 angles
10 sides and 10 angles
A polygon has as many angles as sides, so a polygon with 10 sides (decagon) would have 10 angles.
A decagon has 10 angles (and sides)
A square has 4 angles, so ten squares have 10*4 = 40 angles.
