The triangles are congruent, which means the angles are congruent as well. Therefore, we can set angles ADC and ABC equal to each other to solve for x:
100=2x+8
92=2x
46=x
Therefore, A is correct

well first you could see how many words he types per min. (228/4 = 57)
so if x is the # of mins, y = 57x
good luck!
