Question

find the angle of x and y​

Answer 1

$\huge \fbox \red{Answer}$

x + 90° = 180° [linear pair]

x = 180 - 90

x = 90°

∠DAB + ∠BAC = 180° [linear pair]

120° + ∠BAC = 180°

∠BAC = 180 - 120

= 60°

∠BAC = y = 60°

Answer 2

$\huge{ \underline{\boxed{\red{ \color{red}{\textsf {\textbf{An}{\color{blue}{\textbf {\textsf{sw}}{\color{green}{\textbf{\textsf{er}}}{\color{orange}{\textsf{\textbf{~:-}}}}}}}}}}}}}$

x + 90° = 180° [linear pair]

x = 180 - 90

x = 90°

∠DAB + ∠BAC = 180° [linear pair]

120° + ∠BAC = 180°

∠BAC = 180 - 120

= 60°

∠BAC = y = 60°
