The angles of an equilateral triangle are congruent. If x represents the measure of one angle of an equilateral triangle, which equation represents the sum of the angle measures of the triangle?%0D%0A(1 point)%0D%0AResponses%0D%0A%0D%0Ax + x = 90°%0D%0Ax + x = 90°%0D%0A%0D%0Ax + x + x = 90°%0D%0Ax + x + x = 90°%0D%0A%0D%0Ax + x = 180°%0D%0Ax + x = 180°%0D%0A%0D%0Ax + x + x = 180°
The equation that represents the sum of the angle measures of the equilateral triangle is:
x + x + x = 180°
