Consider the figure
Alex Ar [27]

Answer: 72 degrees for a, 108 degrees for b

Step-by-step explanation: Since the ratio of a to b is 3 to 2, 3x+2x would be 180 degrees. Performing addition and division, we would get 36 for x, and substituting it would get 72 degrees for a and 108 degrees for b. Hope this helps! (Could I please have brainliest?)
