Answer:
x=60°
Explanation:
Equilateral and Equilangular triangles always have equal angles. Since the angles of a triangle have to always add up to 180°, all of the angles of both of these triangles, including x, have to be 60; There are 3 angles in a triangle. If all the angles are equal and they must add up to 180°, then the angles must be equal to 180 if they are multiplied by 3. Because 3×60=180, All angles are 60° and therefore x=60. The lines through the sides of the triangles represent that they are equilateral triangles.
