Answer:
it should be 40º but it doesn't look like that's an option...
Step-by-step explanation:
so we know that the inside of a triangle is equal to 180º and for the triangle on the right we already have two angles. so we can add the angles (41 + 72 = 113) and then subtract that from 180 to find the missing angle.
180 - 113 = 67º
now we also know that vertical angles are congruent/the same. so the vertice that is connecting the two triangles is also 67º. we can do the same thing we did with the other triangle, add the angles up and subtract from 180.
67 + 73 = 140
180 - 140 = 40º
we know this is true because when you add all the angles up it equals 180.
67 + 73 = 140 + 40 = 180
44 would put it at 184º which is not correct, and 150 would put it at 290ª which is also not correct...
