Answer:
Step-by-step explanation: Step 1: Isolate the absolute value expression.
Step2: Set the quantity inside the absolute value notation equal to + and - the quantity on the other side of the equation.
Step 3: Solve for the unknown in both equations.
Step 4: Check your answer analytically or graphically.
Weird. I think you just need to look if the point falls on the shaded area. But only (-5,5) does ...
According to the trigonometric functions, we can see that angle x can be found through the one that involves the adjacent side and the hypotenuse, which in this case is the cos,

then, if we apply the inverse we can find the value of x,

Answer:
The second answer, cause it best shows the equation, but they just moved the numbers around. It is also the only equation with all the same numbers used in the original equation, too
The lines are reciprocal because they cross to form an X. Also 4/5 is the reciprocal of 5/4
