Answer:

70°

Step-by-step explanation:

x = [tex]cos^{-1}[/tex]([tex]\frac{3.4}{10}[/tex]) ≈ 70°

Answer:

<BAC= 70 degrees.

Step-by-step explanation:

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

x=[tex]cos^{-1} \frac{3.4}{10}[/tex]

Or ,[tex]x=cos^{-1} 0.34[/tex]

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.
