6 is added to itself z many times whilst z is multiplied by itself 6 times.
A) <DAE = 180-126 = 54
b) <EBC = 90 - 48 = 42
c) <BAE = 180-48-54=78
I think its 61.64 im not 100% sure but I hope this helps
The sum of the interior angles of a triangle is 180. Add the three measures given and if you get 180 then those can be the interior angles of a triangle.
