<h3>As we know that sum of three angles of triangle is 180º.</h3>
we have


<h3>

The angles a and c are equal so,</h3>
- cb = ab. [ sides opp to equal angles are equal]
so x is also 16
<h3>

Now we have two side we can easily find the third side by P.G.T</h3>
<h3>so the r is root 512 and x is 16.</h3>
Hope it helpa
