Answer:
117
Step-by-step explanation:
The figure is five sided, therefore the sum of the angles = (5-2)180
= 3*180
= 540
113 + 123+97+90(since its right angles)+y(unknown) = 540
423 + y = 540
y = 540 - 423
y = 117
Let the angle vertically opposite to y be z
y = z (vertically opposite angles)
z = 117
x = 117 (Corresponding angles are equal)
