The letter R is on the yellow section, which indicates the yellow area is plane R.
Now see what points and lines are on the yellow sections.
Point M, point R, line F are all in the yellow area. Point X and Y are at the intersection of the two planes, so could be part of both.
Based on the provided answers, the answer would be: Point M and line f.
First we find the measurement of dark dot .
ANd for that we have to use the formula of the angle formed by the intersection of chord .
Let the dark dot be t.
So we have

t and z are linear pair and sum of angles of linear pair =180 degree.
So we get

Solve for N by simplifying both sides of the equation, then isolating the variable.
N=700
