Hope it helps

Answer 2

Answer:

hi bro it's easy come on

this is a triangle right

in a triangle the sum of interior degrees = 180°( it is formula)

angle a plus angle b plus angle c is 180 degree

therefore

50 + b + 77 = 180

b + 127= 180

b = 180 - 127

b = 53 °

so b is 53 °

you gei it right

please mark me brainliest.
