- Complementary angles add to 90 degrees.
- Supplementary angles add to 180 degrees.
- Vertical angles are equal.
So, the answers are (in degrees):
6) 47, 137, 43
7) 49, 131, 49
8) 18, 72, 18
9) 13, 77, 167
Answer:
72.3
Step-by-step explanation:
Given that:
The arithmetic sequence:
The first term of the sequence 
= 3 since k = 0
i.e (3 + 0.26(0)) = 3
The last term of the sequence 
= 6.64
i.e (3+ 0.26(14)
= (3 + 3.64)
= 6.64
Total no of terms = 15 i.e from 0 to 14
∴
The partial sum of the arithmetic sequence = 
= 72.3
