Answer:
The lengths of the other sides is equal to 10 units
Explanation:
we know that
An equilateral triangle is a triangle that have three equal sides and three equal interior angles (each internal angle measure 60 degrees)
so
If the triangle has two interior angle measures of 60° and 60°, then the measure of the third interior angle must be equal to 60 degrees (remember that the sum of the interior angles in a triangle must be equal to 180 degrees)
Therefore
The triangle is an equilateral triangle and the length of the three sides is equal to 10 units
