Distance to A= 119mi
Disy¿tance to C=77mi
angle=34.6°
We have to find h, the angle that curts h will be half of 34.6, is a bisector
Using trigonometric to find h:

Isolating h:

Using the Pythagorean theorem we calculate x:
![\begin{gathered} 119^2=h^2+x^2 \\ x=\sqrt[\placeholder{⬚}]{119^2-h^2}=\sqrt[\placeholder{⬚}]{119^2-113.6^2}=35.4 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/9p1vv4v9awd5fxmmjy0vgsof46ovrcdafm.png)
Now, we will use tan function:

The answer is: 70.78 mi.
