Answer:

<BAC= 70 degrees.

Step-by-step explanation:

The given equation to find angle BAC that is x is :

x= $cos^{-1} \frac{3.4}{10}$

Or , $x=cos^{-1} 0.34$

Using calculator to find the arc of cosine0.34 we have :

x=70.1231

This when rounded to nearest whole degree is 70 degrees.

<BAC= 70 degrees.
