Item 2
In this figure, lines m and n are parallel and intersect transversal t. Also, m∠7=115° .
What is m∠3 ?
115º
65º
25º
I don't know.
Horizontal parallel lines m and n are intersected by diagonal transversal line t which rises from left to right. The four angles formed where line t intersects line m are labeled 1, 2, 3, and 4 starting with the top left angle and going clockwise. The four angles formed where line t intersects line n are labeled 5, 6, 7, and 8 starting with the top left angle and going clockwise.
