Answer: Fourth option is correct.
Step-by-step explanation:
Consider Δ XYZ,
We know that "Sum of interior angles of a triangle is supplementary."
So, we have given that
m∠X = 34°
m∠Z = 26°
so, it becomes, according to the above statement:
[tex]\angle X+\angle\ Y+\angle Z=180^\circ\\\\34^\circ+\angle Y+26^\circ=180^\circ\\\\60^\circ+\angle Y=180^\circ\\\\\angle\ Y=180^\circ-60^\circ\\\\\angle\ Y=120^\circ[/tex]
Hence, Fourth option is correct.
