The answer is B) 18:) hope this helps
Answer:
111
Step-by-step explanation:
NP = (S x 1.10) - 10
OP = NP / .9
10 + y = 18
- 10 - 10
y = 8
Interior angles of a triangle, when added, = 180
so < A + < B + < C = 180
41 + 90 + < C = 180
131 + < C = 180
< C = 180 - 131
< C = 49
< C + < D + < E = 180.....because when added they form a line
49 + 32 + < E = 180
81 + < E = 180
< E = 180 - 81
< E = 99 <======
You take 187 away from 2431
