Find C with angles in triangle sum to 180
A + B + C = 180
C = 180 - A - B
C = 180 - 43.0467020 - 25.9
C = 111.1
Answer:
D
Step-by-step explanation:
the domain of this is x>=7
the range is x<=1
so 6 is in neither

Answer:
I believe its 57.
Step-by-step explanation:
180-66=57.
57+57+66=180
Answer:
B=208.72
Step-by-step explanation:
June 22
July: 22+ 22x (1+10%) = 46.2
Auq: 46.2+ 22 (1+10%) x (1+10%)= 72.82
Sep: 72. 82+ 22 (1+10%)³= 102.102
Oct: 102.102 + 22 x(1+10%)⁴= 134.3122
Nov: 134.3122 + 22×(1+10%)⁵= 169.74342
Dec:169.74342 +22(1×10%)⁶ =208.717762
=208.72
