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.

Answer:
Angular velocity:
(
)
Linear velocity:
(
)
Step-by-step explanation:
The gear experiments a pure rotation with axis passing through its center, the angular (
), in radians per second, and linear velocities (
), in inches per second, of a point on the outer edge of the element are, respectively:
(1)
(2)
Where:
- Rotation rate, in revolutions per minute.
- Radius of the gear, in inches.
If we know that
and
, then the linear and angular velocities of the gear are, respectively:
