We can see that there is a square root in the function.
As the value inside the square root should always be positive, We can conclude that (x - 6) should always be positive and can also be equal to zero.
To solve this you must isolate x. First add 1 to both sides
x² - 1 + 1 = 0 + 1
x² = 1
Now you must take the square root of both sides to cancel out the square from the x
√x² = √1
x = 1 and x = -1
When you take the square root of a number you must remember to take both the positive and negative of the number

Can you add the options?
Also since the options aren't there I'll just help set up.
So angle 1 and angle 3 add up to 90 degrees. Angle 1 and Angle 2 are equal so whatever option has something around those lines is correct.
