If ∠J measures 40°, ∠K measures 90°, and j is 15 feet, then find k using the Law of Sines. Round your answer to the nearest tenth. 9.6 ft 10.4 ft 23.3 ft 154.5 ft

23.3 ft

Step-by-step explanation:

The law of sines gives us:

From the question, <J=40° <K=90°, j=15 feet.

We need to find k.

Let us substitute the values into the equation to get:

This gives us:

To the nearest tenth, k=23.3 ft.

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.
