Question

in the figure M is the midpoint of the line AB . conpute the other two angles of angle ABC
​

Answer 1

Answer:

The other two angles are 50° and 80° because as you said that M is midpoint then the triangle is divided two equal halfs then both the sides are same so if one 50 then other will also be 50 do 50+50 +x = 180° so x= 80°
