The tangent is defined as:
Given a value for the tangent, there are two angles with the same tangent, one of them being and the other
+180°.
We are given:
The angle is the inverse tangent:
Using a scientific calculator, we find the first angle:

The second angle is found adding 180°:
x=70°+180°=250°
Thus, the values of x are 70° and 250°
