Hope this helps!
Each of the angles in a triangle are 60 degrees, so when you add them together, you get 180
60+60+60=180
It Is D because pulling out a yellow marble is INDEPENDENT to pulling out a green marble which is also independent. hope I helped :]
The first thing we will do is define an equilateral triangle:
In geometry, an equilateral triangle is a regular polygon with three equal sides. In traditional Euclidean geometry, equilateral triangles are also equiangular, that is, the three internal angles are also congruent to each other, each angle with a value of 60 °
Every equilateral triangle consists of three equal sides and three congruent angles.
Therefore, there can be a triangle with three equal sides (5 centimeters in this case).
