Find the values of a and b.  The diagram is not to scale.

a =  180 - 36

b = 180 - 113

we sum the two given angles, to get 36+113=149

 

360-149=211

 

we see that choice 3 and 4 don't work, because they don't sum to 200, and choice 2 doesnt work because the last digit will be 0, so choice 1 is our answer
