Gary said that a clockwise rotation of 90 followed by a translation 2 units to the right will make the angles coincide. what was gary's mistake?
a. gary did not make a mistake.
b. the translation is correct, but the rotation should have been 180.
c. the rotation is correct, but the translation should have been 2 units up.
d. the transformation should have been a reflection across the line x = 2.

B.The translation is correct, but the rotation should have been 180°.

Step-by-step explanation:

A 90° - clockwise rotation would only turn the angle sideways.

I hope this helps you out alot, and as always, I am joyous to assist anyone at any time.

step-by-step explanation:

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.
