The sum of the interior angles of a triangle = 180 degrees. So, all of the angles on the inside of the triangle will add up to 180.
60 + 40 + ? = 180
100 + ? = 180
? = 80
The missing angle in the triangle is 80 degrees.
Hope this helps!
210 is ur answer if it’s two tens then it’s 21 and then 1 one so 1 then times 10
The answer is 2, you subtract 4 from 2 and get 2 and then multiply by 1
