Respuesta :

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.

Remember that a straight line = 180°

Angle next to 121°: 180 - 121 = 59
Angle next to 121° = 59°

Angle next to 144°: 180 - 144 = 36
Angle next to 144° = 36°

180 - 59 - 36 = 85

angle  next to n = 85°

180 - 85 = 95

n = 95°, or D

hope this helps
