Question

Find the value of x and y in the given triangle's given below ​

Answer 1

$\implies \: \: \tt x + y + 40 = 180 \degree$

$\tt \implies \: \: 80\degree + y = 180\degree$

$\tt \implies \: \: y = 180\degree - 80\degree$

$\tt \implies \: \: x = 40\degree$

$\tt \implies \: \: y = 100\degree$

Answer 2

Answer:

\implies \: \: \tt x + y + 40 = 180 \degree⟹x+y+40=180°

\tt \implies \: \: 80\degree + y = 180\degree⟹80°+y=180°

\tt \implies \: \: y = 180\degree - 80\degree⟹y=180°−80°

\tt \implies \: \: x = 40\degree⟹x=40°

\tt \implies \: \: y = 100\degree⟹y=100°
