Answer:
[tex]\text{129.868}\degree[/tex]
Explanation:
Here, we want to get the approximate angle to the other landmarks
To get this, we need a diagram that properly represents the information
We have this as follows:
To get the value of the marked angle, we can use cosine rule since we have all the sides
We have it that:
[tex]\begin{gathered} e^2=c^2+t^2\text{ -2ct CosE} \\ 2^2=0.9^2+1.3^2\text{ -2(0.9)(1.3) cos E} \\ 1.5\text{ = }-2.34\text{ cos E} \\ m\angle E\text{ = }\cos ^{-1}(-\frac{1.5}{2.34}) \\ \\ m\angle E\text{ = 129.868}\degree \end{gathered}[/tex]
