Answer 1

Answer:

x = 123°

Step-by-step explanation:

57° + x = 180° ( linear pair is equal to 180°)

x = 180° - 57°

x = 123°

Answer 2

$\huge \red{answer \: }$

$\bold{angle \: a \: b \: c \: is \: straight \: angle \: }$

$\bold{ie \: abc = 180}$

$\bold {angle \: abd \: = 57 }$

$\bold{then \: angle \: x = abc - abd}$

$\bold{x = 180 - 57}$

$\bold{x = 123}$
