Answer :

Answer:

33.4°

Step-by-step explanation:

[tex]AB=22tt[/tex]

[tex]BC=34tt[/tex]

[tex]AC=40ft[/tex]

[tex]cos\ C=\frac{AC^2+BC^2-AB^2}{2AC\bullet BC}[/tex]

[tex]=\frac{{40}^2+{34}^2-{22}^2}{2\times40\times34}[/tex]

[tex]=\frac{1600+1156-484}{2720}[/tex]

[tex]=\frac{2272}{2720}=\frac{71}{85}[/tex]

[tex]< c=arccos\left(\frac{77}{85}\right)\ \ \ \ \ \left\{\begin{matrix}the\ nearest\ tenth\\0.1\\\end{matrix}\right\}[/tex]

[tex]< C\thickapprox 33.4\textdegree[/tex]

[tex]Answer:33.4\textdegree[/tex]

I hope this helps you
