Answer:
-10/3 is the answer
Step-by-step explanation:
Given are two complex numbers as
Recall Demoivre theorem as
(cosA+isinA)(cos A+isin B) = cos(A+B)+isin(A+B)
Hence here we have sum of angles as
A+B = 63+117 =180
=
Since sin180=0 and cos 180=-1
The difference of twice a number and six is four times the number. Find an

Answer: 27
Step-by-step explanation:
The given sequence : 13, 24, 35, ....
Here, first term : a= 13
Common difference: d=24-13 =11
The nth term of arithmetic sequence is given by :-
It is given that the nth term is 299, so put
Subtract 13 from both sides , we get
Divide both sides by 11, we get
Add 1 on both sides , we get
Hence, the value of n= 27
