Solve dy/dx = (1-x)(1-y)

Step-by-step explanation:

We begin with the differential equation

Firstly, we need to get the and as well as the and on the same sides as each other

To do this, we can multiply each side by and divide each side by

Doing this will give us the following differential

Now, we can integrate each side

Now, we need to solve for y

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

answer: this is not a question
