Answer:
16  1/12
Step-by-step explanation:
The LCD of 6 1/3 + 5 1/2 + 4 1/4 is 12; 12 is evenly divisible by 3, 2 and 4.
We can rewrite this expression as:
6 + 5 + 4 + 1/3 + 1/2 + 1/4, or
     15        +4/12 + 6/12 + 3/12, or
     15         + 13/12, or
      16  1/12
 
        
             
        
        
        
 1) Δ ABC
m∠B + m∠C + m∠BAC = 180⁰
2) m∠DAB + m∠BAC = 180⁰ because m∠DAB and m∠BAC are supplementary angles.
3) m∠B + m∠C + m∠BAC = m∠DAB + m∠BAC 
m∠B + m∠C = m∠DAB
32⁰ + x = 98⁰
x=98 - 32 = 66 ⁰
Answer: A. 66⁰.
