What is the value of x 124 62 68 12

In the given triangle, two sides are equal, so the triangle is an isosceles triangle.

And in an isosceles triangle, base angles are equal.

And it is given that one angle is 56 degree, so the other base angle is 56 degree too .

And the sum of measurements of angles of a triangle is 180 degree.

So we will get

Correct option is the third option .

4) is the opposite function of 3), and vice versa. Because f(x) =2x-1 and  its opposite f(x)=-2x+1. And we can see them both in pictures 3 and 4.

Step-by-step explanation:

A piecewise function is a function defined in a sequence of  intervals. The most known piecewise function is the modular function. (1st picture)

An opposite function is given by f(x)=-x of f(x)=x

The following pictures describe the following functions:

1) f(x)=-|2x|+2

2) f(x)= 2.34x-2.34 and f(x)= -2.34x-2.34

Notice how the second function express the opposite line, by the opposite angular coefficient.

3) f(x) =2x-1 and f(x)=-2x+1

4) f(x) = -2x+1 and f(x)=2x-1

Different intervals but the same functions are graphed in 3 and 4. So the graph of f(x)=2x-1 and its opposite f(x)=-2x-1
