Answer:
x = 30
Step-by-step explanation:
In an arithmetic sequence, any given term is the average of the two terms that come before and after. The middle term of this sequence must be ...
2sin(3x) = (-11 +15)/2
sin(3x) = 1 . . . . . . . . . . simplify and divide by 2
Then the value of 3x must be 90°, so ...
x = 90/3 = 30
There is one value of x in the interval [0, 90] that makes this sequence arithmetic: x = 30.
No at least two side need to be parallel to be that so almost anything will be your answer

and 
LHS=
=RHS
7x + 1 = 2(2x - 1) + 3(x + 1)
7x + 1 = 4x - 2 + 3x + 3
7x + 1 = 7x + 1
