Answer: B. They are alternate interior angles, so angle 3 also measures 130°.
Step-by-step explanation:
Here, according to the given figure, lines a and c are parallel lines.
And pipe cleaner is a transversal which is passing through to these parallel lines.
Therefore, by the property of parallel lines, the corresponding and alternative exterior or interior angles made by the common transversal ( pipe cleaner) on the lines a and c must be equal.
And, Here
and
are alternative interior angles by lines a and c with the same transversal, So, they must be equal.
Thus, ![\angle 3=130^{\circ}](https://tex.z-dn.net/?f=%5Cangle%203%3D130%5E%7B%5Ccirc%7D)
