Answer:
-5° < x < 26°
Explanation:
The given parameters are;
The length of the rays forming the 62° = The length of the rays forming the 2·x + 10°
The length of the side opposite the 62° = 15
The length of the side opposite the 2·x + 10° angle = 14
Therefore, by construction, we have;
2·x + 10° < 62°
2·x < 62° - 10°
2·x < 52°
x < 52°/2
x < 26°
Also, we have that the angle 2·x + 10° is real, therefore;
0 < 2·x + 10°
-5 < x
Which gives;
-5° < x < 26°.
