This is simple. You will subtract 76 from 180. You will get 104. Then from there you will divide 104 by 2. You will get 52 which is your answer. This is the answer because this is a Isosceles Triangle.

Sides EF and DF are equal so that is an isosceles triangle and therefore angle D equals angle E
All triangles have angles that sum to 180 degrees.
180 = angle D + angle E + angle F
180 = angle D + angle E + 76
104 = angle D + angle E
and since angle D = angle E
they both equal 52 degrees.
