Simplify by combining like terms to
-n+4=8n-5
subtract 8n from both sides
-n+4-8n=8n-5-8n
-9n+4=-5
subtract 4 from both sides
-9n+4-4=-5-4
-9n=-9
Divide both sides by -9
-9n/-9=-9/-9
n=1
hope this helps!
Answer:
If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent. If two angles and the non-included side of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent. This is an extension of ASA.
