Ф = 3π/4. Transform it into Rectangular (or Cartesian) form .
The coordinates of Ф are x ,y in rectangular form ==> so:
tan(Ф) = y/x and y=x . tan(Ф) ==> y= x. tan(3π/4). we know that tan(3π/4)= - 1
Hence y = - x

Step-by-step explanation:As you can see all other question have 1 before 1 over 9 which 1 over nine is about 0.1111...
Answer:
x=16 and y=9
Step-by-step explanation:
2y+30=3y+21[Diagonals of parallelogram are equal]
30-21=3y-2y
y=9
3y=2x-5[Diagonals of parallelogram are equal]
3×9=2x-5
27=2x-5
2x=27+5
x=32/2=16
Given the inequality;

Let's convert it to slope intercept form;

So, the slope of the line is 2/3 which is positive, and the intercept on the y axis is 4.
