Answer:
TBH its a Link of this its call pdf and it tell yuu all your answer
Step-by-step explanation:
B) 40, knowing that DCA is 155 is helpful because then you can figure out angle C. 180-155 is equal to 25. Then, 115+25= 140. 180-140= 40
8 3/4+n+2 3/8+ 23 1/8
8 3/4+n+ 25 4/8
35/4+ n+ 204/8
70/8 +n+ 204/8
274/8 +n
n= -274/8= -25 1/2
