I think.....
The answer to your question is B. Hope it helped !
Answer:
445
Step-by-step explanation:
(1) it can be both exterior of vertex or base. 180-130=50°
vertex is 50°: base=(180-50)/2=65°
base is 50°: vertex= 180-2*50=80°
vertex 50 base 65; vertex 80, base 50
(2)base=180-130=50°
vertex=180-2*50=80°
base 50 vertex 80
The answer is y -2 = -3x -3
