Answer:
1÷y/-x
Step-by-step explanation:
1÷y/-x
1×-x/y
-x/y
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
Okay. 10×5=50cm^2 is the area of the rectangle
The height of the triangle is (18-10)=8cm
So (8×5)÷2=20cm^2
50+20=70cm^2 is the area of the composite shape
Your two equations for this question would be:
n + d = 234
5n +10d = 16.10
So with that you must take your two equations and make them equal to eachother.
Hope this helped :)
