Find the value of x.

x = 6

Concept:

From the given graph, we can see that it is an isosceles triangle since the two base angles are congruent.  

In geometry, an isosceles triangle is a triangle that has two sides of equal length.  

If you are still confused, you may refer to the attachment below for a graphical explanation or tell me.

Solve:

Given information

One side = 6

Second side = x

Given expression deducted from the definition of an isosceles triangle

Second side = First side

Substitute values into the expression

Hope this helps!! :)

4 + 5 7/9= 9 7/9

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.
