HELP! Find the measures of ALL tbe sides of the equilateral triangle EFG.

Answer:
x=
Step-by-step explanation:
Since all the sides are congruent then set two of the equations equal to each other
6x-9=2x+19
4x-9=19
4x=28
x=7
Substitute
6(7)-9= 33
2(7)+19= 33
3(7)+12= 33
all sides are congruent(equal).
