In the diagram, how many angles must be supplementary with angle 14?

Answer:
2
Step-by-step explanation:
angles 13 and 15 are supplementary with 14
since none of the lines are parallel
Answer: There are two angles.
Step-by-step explanation:
Since we have shown in the figure:
[tex]\angle 14+\angle 15=180^\circ[/tex] ( ∵ Linear pair)
Similarly,
[tex]\angle 13+\angle 14=180^\circ[/tex] ( ∵ Linear pair)
So, we can see that
there are two angles that must be supplementary with angle 14.
Hence, there are two angles.
