okay well first off do you know what it means to be congruent?

anonymous · Answer

Yes

eyust707 · Answer

okay sweet so we know the triangles are exactly the same

eyust707 · Answer

that means that the sides are equal in length

anonymous · Answer

Yes =] I think the answer is 3 ?

eyust707 · Answer

hehe okay this one is trying to trick you

anonymous · Answer

Oh no xD I get these wrong a lot.

eyust707 · Answer

since they are congruent the side that is 5 must match up with the other triangles side that is 5 and the side that is 4 must match up with the other side that is 4

eyust707 · Answer

its weird because they have not drawn it to look that way.. but it never said it was drawn to scale

eyust707 · Answer

so that means that:
5 =5

eyust707 · Answer

4 = 4

eyust707 · Answer

and

2x +2 = 3x -1

eyust707 · Answer

solve for x and your golden!
