For this question i thought that angle 1 was 109 degrees. I drew lines from the center to angle A and B which i made 90 degrees. Then i split 38 in half to get 19 to make 2 90 degree angels. Then i solved for the remaining angle (AOP) which gave me 71. Then with 71+90+?=180 (sum of a triangle) which gave me 54.5. Which was also the same for the other side as they are equal. so I times 54.5 by 2 to get 109. I just dont know if i did it right and what i would say is my proof for finding that? Or if there is a way faster way of solving that?
