Answer:
30 + 18x = 6(5+3x)
Step-by-step explanation:
for this all you have to do is distribute the 6 by doing 6 x 5 = 30 and
6 x 3 = 13 and then you just have to add them together to get
30 + 18x = 30 +18x
Answer is 18 and value of x is 0
Answer:
B
Step-by-step explanation:
Answer:
lines ab and ef
Step-by-step explanation:
they are the same length, this what congruent means
Answer:
∠DFE ≅ ∠DFG
Step-by-step explanation:
we know that
Triangles are congruent by SAS, if any pair of corresponding sides and their included angles are equal in both triangles
In this problem we have that
The pair of corresponding sides that are equal are
EF=GF and DF (is the same side for both triangles)
The included angle are ∠DFE and ∠DFG
therefore
The additional information needed to prove that triangles DEF and DGF are congruent by SAS is that angles ∠DFE and ∠DFG are equal
so
∠DFE ≅ ∠DFG
