Find the value of x.
Round to the nearest degree.

Please show your work if possible.

For the given triangle, x = 51°.

Step-by-step explanation:

Step 1:

In the given triangle, the angle is x°. The opposite side has a length of 7 units while the hypotenuse of the triangle measures 9 units. To calculate the value of x, we determine the sin of angle x where we divide the length of the opposite side by the length of the hypotenuse.

sin x°

Step 2:

The length of the opposite side = 7 units.

The length of the hypotenuse = 9 units.

So x° = 50.986°, rounding this off to the nearest degree we get x = 51°.

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.
