I'm not sure what the ray exactly is but some examples of ray names are ray RT or ray TR. You basically switch the letters.
Answer:

Step-by-step explanation:
Use the Pythagorean theorem. 
a and b are the two side lengths
c is the hypotenuse (value across from the right angle)
Plug in the values that you are given.

Solve for x


x=

The inequality that represents the graph in the box is

Given :
The graph of the linear inequality
Lets pick two points from the graph to frame the linear equation
Slope intercept form of the equation is

Where m is the slope and b is the y intercept
y intercept is (0,6) from the graph
so b=6
Now we find out slope m using formula
Pick two points (0,6) and (2,0)

m=-3
So the equation is 
Now we check the inequality sign by testing any point on shaded area
lets pick (4,0)
lets plug in 4 for x and 0 for y

The inequality for the given graph is

we cannot use >= sign because we have dotted lines
