Answer:

80.5°

Step-by-step explanation:

The applicable trig function is the tangent.

Tan = Opposite/Adjacent

In this scenario, the side opposite the angle is the tower height, 324 m. The side adjacent is the distance to the tower, 54 m. Then the angle α is related by ...

tan(α) = 324/54

The value of the angle with this tangent is found using the arctangent function:

α = arctan(324/54) ≈ 80.5°

She should set her binoculars to 80.5°.
