Answer:
No
Explanation:
For the triangle to be equilateral then all 3 sides must be congruent.
Equate any 2 sides and solve for x
3x + 1.2 = 2x + 6.2 ( subtract 2x from both sides )
x + 1.2 = 6.2 ( subtract 1.2 from both sides )
x = 5
then the measures of the 3 sides are
2x + 5.2 = 2(5) + 5.2 = 10 + 5.2 = 15.2
3x + 1.2 = 3(5) + 1.2 = 15 + 1.2 = 16.2
2x + 6.2 = 2(5) + 6.2 = 10 + 6.2 = 16.2
the 3 sides are not congruent thus triangle is not equilateral.
However, the 2 sides 3x + 1.2 and 2x + 6.2 are both 16.2
Then the triangle is isosceles
