If O is an angle in standard position and its terminal side passes through the point (8,5), find the exact value of cot 0 in simplest radical form.

8/5

Step-by-step explanation:

Since the angle passes through 8,5. The horizontal side length is 8. The vertical length is 5 so now we must find the hypotenuse or radius side. Using the pythagorean theorem, that can be accomplished.

So know me gonna to find our trig functions. Cot or cotangent is x/y so we plug that as x=8, y=5.

so the answer. is 8/5

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
