Question

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

Answer 1

x=

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).
