Question

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

Answer 1

Answer: There are two angles.

Explanation:

Since we have shown in the figure:

`\angle 14+\angle 15=180^\circ` ( ∵ Linear pair)

Similarly,

`\angle 13+\angle 14=180^\circ` ( ∵ Linear pair)

So, we can see that

there are two angles that must be supplementary with angle 14.

Hence, there are two angles.

Answer 2

2

Explanation:

angles 13 and 15 are supplementary with 14

since none of the lines are parallel
