a=44, b= 58

Step-by-step explanation:

You look at the first triangle that gives you the two angles, and with the rule that every triangle's angles inside it need to add up to 180 degrees, you can determine that the missing angle is 46 degrees, which translates over to the other triangle, meaning that a would be 44 degrees.

The other triangle has two identical angles, being 61 degrees, which helps translate to the smaller triangle, again allowing you to infer that b is 58 degrees
