Answer:
x = 5
Step-by-step explanation:
The arc subtended by the marked angle is ...
360° -226° = 134°
The measure of the marked angle is half this, so we have ...
15x -8 = 134/2
15x = 75 . . . . . . . add 8
x = 5 . . . . . . divide by 15
The answer would be choice C.
Perpendicular lines cross each other and form a right angle as you can see marked in the third picture.
