Show that the angles of an equilateral triangle are 60°

Equilateral triangle has all sides equal.For triangles sum of interior angle=180degrees
since for equilateral all sides are equal then let x represent the sides



hence angle of equilateral triangle is 60

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
