Answer:
Range : 0° < x < 17°
Step-by-step explanation:
In any triangle, the smallest angle is opposite to the smallest side.
So, In ΔABD , the side which faces ∠ABD is AD whose length is 22 units.....(1)
And, in ΔCBD, the side which faces ∠CBD is CD whose length is 30 units....(2)
Now, from equations (1) and (2) We get,
∠ABD < ∠CBD
So, ∠ABD lies between 0° to 34°
[tex]\Rightarrow 0 < 2\cdot x<34\\\Rightarrow 0<x<\frac{34}{2}\\\Rightarrow0<x<17[/tex]
∴ Range of x is 0° to 17°
