Case 1

$\implies$ x + 68° = 90° [ Right angle ]

$\implies$ x = 90° - 68°

$\implies$x = 22°

Case 2

$\implies$x + 90° + x = 180° [ Linear pair angle ]

$\implies$2x = 180° - 90°

$\implies$2x = 90°

$\implies$x = 90/2

$\implies$x = 45°

Case 3 :-

$\implies$x + 20° + x + 40° + x + 15° = 360°

$\implies$3x + 75° = 360°

$\implies$3x = 360° - 75°

$\implies$3x = 285

$\implies$x = 285/3

$\implies$x = 95°
