Answer:
7m +3
Step-by-step explanation:
To find the perimeter of a triangle, we add up all the sides
m + 3m + 3m+3
Combine like terms
7m +3
Yes, they are.
If the triangles have three corresponding angles equal means that they are either similar or congruent.
The definition of congruent means that the sides have the same length. That is precisely what the statement says.
So, being the lengths of the corresponding angles the same the two triangles are identical, this is they are congruent.
Last option is your answer ( 0.00000991)
1/3(9x) =3x
1/3(18) =6
3x+6-5
Then you do
-(x)=-x
-(3)=-3
5x-x-3 = 4x-3
4x-3=3x+6-5
4x-3=3x+1
x=4
