Two angles in a triangle are marked as congruent. The third angle is labeled 70°. Which side of the triangle is opposite of the third angle? the middle side

the two shorter sides

the longest side

the shortest side

Step-by-step explanation:

Here third angle=70

the other two angle =180-70/2=110/2=55

so,

The longest side of the triangle is opposite of the third angle

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.
