Answer:
43 °
Step-by-step explanation:
In the statement they mention the height and in addition to that the horizontal distance where a right triangle is formed, therefore we can apply a trigonometric ratio to calculate the angle, in this case it is the tangent, which relates the two legs of the angle:
Tan A ° = opposite / adjacent
opposite = 66, adjacent = 72, replacing we have:
Tan A ° = 66/72 = 0.9166
A ° = arc tan (0.9166)
A ° = 42.51
That is, the angle of elevation is 43 °
