Answer:
Step-by-step explanation:
Let the missing angle be x then .,
81 + 62 + x = 180 (being sum of angles of triangle )
143 + x = 180
x = 180 - 143
x = 37
<em>Therefore the missing angle is 37</em>
154/10=15.4. Then apply greatest integer function (smallest integer larger than that number) to get 16.

AB is the longest side, so ∠C is the largest angle.
use law of cosine: 16²=9²+12²-2*9*12cosC
216cosC=81+144-256=-31
cosC=-0.14352
C≈98
