The correct answer is A) 29°, 82°, and 69°
Explanation:
A triangle is a polygon or shape with three sides, three vertices, and three angles. Additionally, in all triangles no matter if they are equilateral (triangles with three equal sides), scalene (triangles with three unequal sides) or isosceles (triangles with two equal sides), the angles add up to 180° and therefore, you need three angles that add up to 180° to construct a triangle. According to this, the set of angles that can be used to create a triangle are 29°, 82°, and 69° because 29 + 82 + 69 = 180° which is the total sum up of all the angles of any triangle.
