This is a fun question. If the triangle rests on one of its sides as a base, then the altitude of the triangle, a line drawn from the apex of the triangle to the base, divides the triangle into two right angle 30o,60o, 90o, triangles. For convenience let each of the equal sides of the triangle 2 units. Then Pythagorus tells us that the base of each of these right triangles is 1 unit and the altitude is √3. This leads directly to
sin(30o) cos(60o) 1/2 and cos(30o) sin(60o) √3/2 0.866 rounded. You can also use one of these right angle triangles to find the sine and cosine of 15o but the algebra gets a little messy.

An oxymoron. An equilateral triangle cannot be obtuse; an obtuse triangle cannot be equilateral.
What is a real life example of an equilateral triangle?
An equilateral triangle is a triangle in which all three sides are equal. The yield sign on highways is an equilateral triangle.
A triangle with all sides the same length?
is called an equilateral triangle
What is the contrapositive of the statement if it is an equilateral triangle then it is an isosceles triangle?
The contrapositive would be: If it is not an isosceles triangle then it is not an equilateral triangle.
What is the angle of the three sides to an equilateral triangle?
Each angle to an equilateral triangle is 60 degrees and can be worked out by dividing 180 degrees (the sum of all angles) by 3.
Does a equiangular triangle have to be equilateral?
