Well im not good at this ,butt I'll tell you something. An open dot means that point is not included , soo something like y<208 would mean 208 is not included and have an open dot, butt a closed dot means the point is included, such as <_ 450. ( The line is supposed to be under < butt i don't know how to do that.) Hope this helps
Answer:
48
Step-by-step explanation:
50 + 88= 132
in triangle abc,
132+L=180
L=48
1-2m-5m=15
combine like terms
1 -7m = 15
subtract 1 from each side
1-1-7m = 15-1
simplify
-7m = 14
divide by -7
-7m/-7 = 14/-7
simplify
m = -2
