#### Explanation:

The work done will be equivalent to potential energy gained as the object climbs incline of 9 m. So we need to calculate the side opposite the 75 degree angle. 75 degrees is steep angle indeed.

The gives you an idea of the incline steepness

graph{1.5x [-10, 10, -1, 5]}

The hypotenuse = 9m thus

The work done is equivalent to potential energy gained

Thus
