ganeshie8 · Answer

since the triangular parks are congruent, the corresponding lengths will be congruent too :

BC = EF

3x - 4 = x+6

ganeshie8 · Answer

solve x, what do u get ?

anonymous · Answer

x=5

ganeshie8 · Answer

Yes! plug that x value in BC expression and find the length

anonymous · Answer

ummm im not sure how to plug the x value

ganeshie8 · Answer

You have BC = 3x - 4

plug x = 5 above
BC = 3*5 - 4
     =  ?

anonymous · Answer

BC= 3(5)-4= 11

ganeshie8 · Answer

Correct !

ganeshie8 · Answer

Since EF is congruent to BC, its length will be 11 too
