Answer:
<em>Thus, the values of x are 70° and 250°</em>
Step-by-step explanation:
<u>Trigonometric Functions</u>
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:
x=70°
The second angle is found adding 180°:
x=70°+180°=250°
Thus, the values of x are 70° and 250°
