Use The Law Of Cosine To Solve For The Missing Angle In The Triangle Round To The Nearest Whole Degree I Need Help Step By Step Tried To Solve But Want To Make class=

Sagot :

To find x, we use the law of cosines

[tex]16^2=22^2+8^2-2\cdot22\cdot8\cdot\cos x[/tex]

Now, we solve for x

[tex]\begin{gathered} 256=484+64-352\cdot\cos x \\ 256=548-352\cdot\cos x \\ 256-548=-352\cdot\cos x \\ -\frac{292}{-352}=\cos x \\ x=\cos ^{-1}(\frac{292}{352}) \\ x\approx34.2 \end{gathered}[/tex]

Hence, the angle x measures 34.2°, approximately.
