Answer:
A = 70
Step-by-step explanation:
CB is equal to EZ and E equals 35, and E and C are the same, therefore, both E equals 35. Since there's 180 degrees in a triangle, and ABY equals 105, you have to subtract 180 - 105 to get the other angle. When you do that, you get that B equals 75. You have to add E and B (35 + 75), since that's in the same triangle as A. When you do that, you get 110. Subtract 180 - 110 to get A, which is 70.
