Answer:
triangle is equilateral
Explanation:
the sum of the 3 angles in a triangle is 180° sum the 3 angles and equate to 180
2x + 2x + 3x - 30 = 180
7x - 30 = 180 ( add 30 to both sides )
7x = 210 ( divide both sides by 7 )
x = 30
Then
2x = 2 × 30 = 60°
3x - 30 = 3(30) - 30 = 90 - 30 = 60°
Since the 3 angles are 60° then the triangle is equilateral.
