A linear pair is a pair of angles that form a line. And since they form a line, when added, they equal 180.
x = one angle....y = the other one
x + y = 180
x = y + 26
time to sub
y + 26 + y = 180
2y + 26 = 180
2y = 180 - 26
2y = 154
y = 154/2
y = 77 <=== this is one angle
x = y + 26
x = 77 + 26
x = 103 <=== and the other one
Well, the normal force and the force of gravity are equal, however, they travel in opposite directions. Mass never changes and temperature has to do with the ambient environment and the object itself. That eliminates 3 and 4. The force of gravity pulls downwards as we see it, so that eliminates option 1. Your answer is option 2.
Answer: The object would move up or down(Option 2)
