What is the measure of the third angle? The other two are 54degrees 53'55'', and 105degrees 32'43''
--------------
If it's a triangle, the sum of the angles is 180 degs
Add the 2 angles.
105degrees 32' 43''
+54degrees 53' 55''
-------------------------
159 degs 85' 98"
---
98" = 1' 38"
--> 159 degs 86' 38"
86' = 1 deg 26'
--> 160 deg 26' 38"
-----------------------
Subtract that from 180 degs
180 degs = 179 deg 60' = 179 deg 59' 60"
--------------
+179 deg 59' 60"
-160 deg 26' 38"
-------------------
= 19 deg 33' 22"
