The top angle in the middle triangle is 180-121, which is 59.
The right side angle in the triangle is 180-144, which is 36.
The angles of a triangle add up to 180. Therefore, bottom left angle in triangle equals 180-59-36, which equals 85.
N equals 180-the bottom left triangle angle, therefore it is 95 degrees.

Let us take the width of the paper as base, the cut she made be hypotenuse and the paper's length be perpendicular.
Here,
Hypotenuse (H) = 87 inch
Base (B) = 60 inch
Perpendicular (P) = [To be calculated]
As, we can use Pythagoras theorem to find. So by using Pythagoras theorem :
H² = P² + B²

The length of the paper is 63 inches.
