or, 
or, 
Rounding off to the nearest tenth, we have;

Hence,
The value of y is 51.3°.
Answer:
If i did this right the answer would be 69

You want to distribute and then combine the like terms, as per order of operations. Start by multiplying the 2 by -n and -3, so you get -2n-6. Then distribute the -7 to the 5 and 2n, so you get -35-14n. Combine your n’s and constants, and get -16n-41
