3.5 3.4 3.3 3.2 3.1 3 -5.5 -1 -2
Answer:
see explanation
Step-by-step explanation:
Note that cos315° = cos45° and sin315° = - sin45° and
cos45° = sin45° =
= 
Hence
12(cos315° + isin315°)
= 12(cos45° - isin45°)
= 12(
- i
)
= 6
- 6i 
Answer:
18
Step-by-step explanation:
Product of 7 and a number is 126.
Let's form the equation,
→ 7 × x = 126
The required value of x will be,
→ 7 × x = 126
→ x = 126/7
→ [ x = 18 ]
Hence, the number is 18.
