Answer 1

84 degrees

The triangle is isosceles you know this from the 2 congruent sides marked 5

Thus angle F is 48 degrees

To find angle E-
180 - (48 + 48) = 84

Answer 2

Explanation:

Isosceles triangle. so ∠F = 48

∠E + ∠F + ∠D = 180 {angle sum property of triangle}

∠E + 48 + 48 = 180

∠E + 96 = 180

∠E = 180- 96

∠E = 84
