You know only the given information aboutthe measures of the angles of a triangle. Find the probability that the triangle is equiangular.
39. Each is a multiple of 12.

Answers

Since they are multiples if 12

The possibilities are

12, 12, 156

12,24,144

12,36,132

12,48,120

12,60,108

12,72,96

12,84,84

24,24,132

24,36,120

24,48,108

24,60,96

24,72,84

36,36,108

36,48,96

36,60,84

36,72,72

48,48,84

48,60,72

60,60,60

Hence the probability is 1/19 or 0.0526

Final answer:

An equiangular triangle has all angles equal to 60 degrees. A triangle with angles that are multiples of 12 can be equiangular triangle only if each angle is 60 degrees. The probability of this is low due to multiple possibilities of multiple of 12.

Explanation:

In mathematics, a triangle is defined as equiangular if all its angles are equal. For a triangle to be equiangular, each angle must measure 60 degrees because the sum of all angles in a triangle is always 180 degrees.

Note, if each angle of a triangle is a multiple of 12, the only way it can be an equiangular triangle is if each angle measures 60 degrees (which is indeed a multiple of 12). Therefore, for a triangle with angles that are multiples of 12 to be an equiangular triangle, each angle must be 60 degrees.

However, multiple possibilities exist for angles of a triangle that are a multiple of 12, for instance, 12, 72, 96 or 24, 36, 120 etc. Therefore the probability that randomly picked triangle with the given condition is equiangular is relatively very low.
