Answer:Three lines creating six angles
3 angles on top, 3 angles below
Since the top left angle is a right angle
It means the line that divides the top angles from the angles below is bisected by a perpendicular line.
This means the sum of the angles of the top left = 90°
Therefore, x + 61° = 90°
x = 90° – 61°
x = 29°
