Answer:
what do you want us to solve
Step-by-step explanation:
i dont see anything to find a awnser
A + C = 90/190
B + D = 100/190
Therefore answer is H

Let's evaluate ~
The given expression is :

plug the value of x as 3



Therefore, the required value is 20
Answer:
dy/dx = (cos y + y sin x) / (cos x + x sin y)
Step-by-step explanation:
y cos x = x cos y
y (-sin x) + dy/dx cos x = x (-sin y dy/dx) + cos y
-y sin x + dy/dx cos x = -x sin y dy/dx + cos y
dy/dx (cos x + x sin y) = cos y + y sin x
dy/dx = (cos y + y sin x) / (cos x + x sin y)
Okay well here's what I got.
