Question

I don't how brainly is solving this Question can anyone explain me​

Answer 1

Answer:

q° + 4m = 180°

so, q° = 180° - 4m

It means that the value of q° = 180° - 4m

as we all know the sum of two interior angles of triangle is equal to the value of an exterior angle opposite to them

So, as we can see

140° = 2m° + q°

140° = 2m° + 180° - 4m°

140° -180° = 2m° - 4m°

-40° = -2m

-40°/-2° = m°

20° = m°

m° = 20°
