Answer:
a)13 b)no because at 18th term its -345
Answer:
12
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Supplementary angles sum to 180°, hence
3x + 9 + 2x + 2 = 180, that is
5x + 11 = 180 ( subtract 11 from both sides )
5x = 169 ( divide both sides by 5 )
x = 33.8
Hence the smaller angle has a measure of
2x + 2 = (2 × 33.8) + 2 = 67.6 + 2 = 69.6° → B
Answer:
Step-by-step explanation:
b x .15 = 5.10
b=5.10/.15
b=34
