x < 1
To graph this on a number line, plot an open circle at 1 on the number line. Do not fill in the open circle. Shade to the left of the open circle. The shaded region represents all x values smaller than 1.
The graph is shown below.
First, Look at the attached picture as a reference.
Now, using Pythagoras theorem,

Now, lets find the elevation of the sun.
