The approximate angle to the other two landmarks from the Empire State Building is 129.868°
Cosine rule is used to show the relationship between the sides and angles of a triangle. It is given by:
a² = b² + b² - 2bc*cosA
Where a, b, c are the sides and A is the angle opposite to side A.
Let A represent the angle to the other two landmarks from the Empire State Building. Hence:
2² = 1.3² + 0.9² - 2(1.3)(0.9)cosA
A = 129.868°
The approximate angle to the other two landmarks from the Empire State Building is 129.868°
