Step-by-step explanation: In geometry, a vertex is where two rays share a common endpoint or where they interest each other.
The rays are called the sides of the angle and
common endpoint is called the vertex.
The vertex is very important when naming angles because
the vertex is always at the center when naming the angle.
Below is an example of two rays that share a
common endpoint which is called the vertex.
Inequalities are used to compare unequal expressions.
The actual comparison is: or
The temperatures are given as:
From the above list, we have:
By comparison,
or
Using absolute values, the inequalities are:
or
Hence, the actual comparison is:
or
