8th grade math problem help?
Solve for angle F using all three of the definitions of vertical, supplementary, and corresponding angles. Explain your reasoning.
Two nearly-vertical parallel lines, m and n are cut by a nearly-horizontal transversal t. A ray extends from the intersection of lines m and t upward and to the left. The angles surrounding the intersection of lines m and t are labeled clockwise from the upper right. Angle a is an acute angle. Angle b is below and adjacent to angle a, and is an obtuse angle. Angel c is to the left of and adjacent to angle b, and is also acute. The ray bisects the obtuse angle opposite angle b resulting in two angles: one is labeled seventy degrees and the other is labeled forty degrees. The angles surrounding the intersection of lines n and t are labeled clockwise from the upper right. The first angle is labeled d, and is acute. Angle e is below and adjacent to angle d, and is obtuse. Angle f is to the left of and adjacent to angle e, and is acute. Angle g is above and adjacent to angle f, and is obtuse.
I need help if you will Thanks! :D
