Step-by-step explanation:
Kindly refer to the image attached in the answer region for labeling of triangle.
<em>AB </em><em>= 16 </em>
<em>BC </em><em>= 19</em>
<em>AC </em><em>= 15 </em>
We have to find the <em>angles </em><em>x</em> and <em>y</em> i.e. .
Formula for <em>cosine rule</em>:
Where
<em>a</em> is the side opposite to ,
<em>b</em> is the side opposite to and
<em>c</em> is the side opposite to .
Similarly, for finding the value of <em>y:</em>
Hence, the values are:
