Answer:
73 degrees
Step-by-step explanation:
The interior angle equals to 180. 73+37+ m<2 = 180. That means angle 2 is 70 degrees. 
m<1 and m<C and equal due to alternate interior angles. That means angle 1 is 37 degrees. 
We know angles 1 and 2 equal to 37 and 73. That means the angles are equal to the interior triangle. 70+37= 107.      180-107= 73 Degrees
