The solution of this equation is x = 5 and   x = 9.
<h3>What is the solution?</h3>
Let us recall that what we have here is a radical equation as follows;
√7x+1 - √x-5 = 6
When we isolate we have';
  √7x+1 = √x-5+6
Taking the square of both sides;
   (√7x+1)^2 = (√x-5+6)^2
Hence;
     7x+1 = x-5+36+12√x-5
-12√x-5 = -7x-1+x-5+36
 12√x-5 = 6x-30
Raising this equation to power 2
144x-720 = 36x^2-360x+900
When we rearrange we obtain;
36x2  - 504x  + 1620 = 0
Hence;
x = 5 and   x = 9

Using equivalent angles, we have that the measures are given as follows:
<h3>What are equivalent angles?</h3>
Each angle on the second, third and fourth quadrants will have an equivalent on the first quadrant.
120º is in the second quadrant, hence the equivalent on the first quadrant is:
180º - 120º = 60º.
The sine on the second quadrant is positive, hence:

The cosine on the second quadrant is negative, hence:

The tangent is given by the <u>sine divided by the cosine</u>, hence:
