We will use the law of sines:

{{{b/sin(B)}}}{{{&quot;&quot;=&quot;&quot;}}}{{{c/sin(C)}}}

b = 200
sin(C) = sin(48&lt;sup&gt;o&lt;/sup&gt;17&#39;) = 0.746444643

But we need angle B:

angle B = 180&lt;sup&gt;o&lt;/sup&gt; - 59&lt;sup&gt;o&lt;/sup&gt;23&#39; - 48&lt;sup&gt;o&lt;/sup&gt;17&#39; = 72&lt;sup&gt;o&lt;/sup&gt;20&#39;

sin(B) = sin(72&lt;sup&gt;o&lt;/sup&gt;20&#39;) = 0.9528381993

{{{200/0.9528381993}}}{{{&quot;&quot;=&quot;&quot;}}}{{{AB/0.746444643}}}

{{{0.9528381993*AB}}}{{{&quot;&quot;=&quot;&quot;}}}{{{200*0.746444643}}}

{{{0.9528381993*AB}}}{{{&quot;&quot;=&quot;&quot;}}}{{{149.2889286}}}

{{{AB}}}{{{&quot;&quot;=&quot;&quot;}}}{{{156.6781524}}}

Edwin&lt;/pre&gt;
