<PRE><B>Question 898490</B>
What is the measure of the third angle? The other two are 54degrees 53&#39;55&#39;&#39;, and 105degrees 32&#39;43&#39;&#39; 
--------------
If it&#39;s a triangle, the sum of the angles is 180 degs
Add the 2 angles.
105degrees 32&#39; 43&#39;&#39; 
+54degrees 53&#39; 55&#39;&#39;
-------------------------
159 degs 85&#39; 98&quot;
---
98&quot; = 1&#39; 38&quot;
--&gt; 159 degs 86&#39; 38&quot;
86&#39; = 1 deg 26&#39;
--&gt; 160 deg 26&#39; 38&quot;
-----------------------
Subtract that from 180 degs
180 degs = 179 deg 60&#39; = 179 deg 59&#39; 60&quot;
--------------
+179 deg 59&#39; 60&quot;
-160 deg 26&#39; 38&quot;
-------------------
= 19 deg 33&#39; 22&quot;
