Answer:

180 degrees

Step-by-step explanation:

Triangles have 3 sides,

A triangle can only have one right angle (90 degrees),

Equilateral triangles have 3 equal sides (60 degrees x 3)

Think of it like this:

A straight line has an angle of 180 degrees,

A triangle has 3 straight lines but only one straight line makes up the degrees of all angles added up.
