the person before me i dont think dod did their math right bc some of their math answers are wrong on 5 through 8 i think it is. 
 NOW HERE'S HOW TO DO IT WITH EXAMPLES OF YOUR QUESTIONS 
in triangles all angles added up cant be more than 180 degrees . basically you take 180 and subtract the known angles and what is left over is the unknown angle 
example question 1.) 180-112-54=14
question 2.) 180-38-25=117. i hope this helps. man i should have typed faster id be first. owell goodluck
