Tan 135 = -1
so rectangular coordinates are (-7 sqrt2, 7 sqrt2)
The answer I got was 59.2
How I got it was that I counted how many years it was I got 16 years multiplied it by 3.7 and got 59.2
1/5, 0.4, 1/2, 0.75
Just convert all of them to decimals first then it should be easy or you .
Well, the first one, I have never worked with before so I'm sry but I can't help you with that one. 3y + x = 4 (x=1) 2y - x = 6 (x=8)
