Question

Please find the value of A and B​

Answer 1

For B :

`{ \sf{b \degree + 76\degree + 90\degree = 180\degree}} \\ \{angles \: of \: a \: triangle \} \\ b\degree + 166\degree = 180\degree \\ b = 180\degree - 166\degree \\ { \boxed{ \boxed{b = 14\degree}}}`

For A :

`a\degree + b\degree = 180\degree \\ \{angles \: on \: a \: straight \: line \} \\`

but b is 14:

`a + 14 = 180 \\ { \boxed{ \boxed{a = 166\degree}}}`
