Answer:

1) 103 degrees

2) 109 degrees

3) 65 degrees

Step-by-step explanation:

1) A line is 180 degrees, so 180 - 77 = 103 degrees. y = 103

2) All the angles in a triangle add up to 180 degrees, so 64 + 45 = 109. 180 - 109 = 135. x = 135

3) same as the last one, 68 + 47 = 115. 180 - 115 = 65. x = 65
