Answer:

Step-by-step explanation:
The sum of the interior angles of a triangle add up to
. Therefore, an equiangular triangle will have each of its angles equal to
. We can then set up the following equation:
.
A decagon has 10 sides. If the polygon is symmetrical, the angle of rotation is given by the following equation:
360 / (number of sides)
Therefore,
360 = 10 = 36.
The interior angles are determined by the following equation:
180 - (angle of rotation)
Therefore,
180 - 36 = 144
The answer is A.
