Answer:
1.45
2. 135
Explanation:
1.  With a triangle all angles have to add up to 180, so what you would do is add up both angles we already know (43+92=135), then we subtract the sum from 180, (180-135=45) now you know the third angle.
2.  Just like a triangle, when finding angles on a line, it has to add up to 180. We already know that point M has an angle of 45 from the last problem, so all we have to do is subtract 45 from 180 (180-45=135). THats the measurement on TMS
 
        
             
        
        
        
First do 12-5, which equals 7.  Next, subtract 1/10 from 2/5.  2/5 is the same as 4/10 if you multiply both the numerator and denominator by 2.  4/10-1/10=3/10. Now add 7 and 3/10.  You will get 7 3/10 as the answer, which is letter C.)
