Answer:
The  tension in the rope is 229.37 N.
Explanation:
Given:
Mass of the block is, 
Coefficient of static friction is, 
Angle of inclination is,  °
° 
Draw a free body diagram of the block.
From the free body diagram, consider the forces in the vertical direction perpendicular to inclined plane.
Forces acting are  and normal
 and normal  . Now, there is no motion in the direction perpendicular to the inclined plane. So,
. Now, there is no motion in the direction perpendicular to the inclined plane. So,

Consider the direction along the inclined plane.
The forces acting along the plane are  and frictional force,
 and frictional force,  , down the plane and tension,
, down the plane and tension,  , up the plane.
, up the plane.
Now, as the block is at rest, so net force along the plane is also zero.

Therefore, the  tension in the rope is 229.37 N.
