Answer:
e = 31
Step-by-step explanation:
The triangle on the left has 2 congruent sides , so is isosceles with 2 congruent base angles of size
=
= 62
Then the interior angle of the triangle on the right is
180° - 62° = 118°
The triangle on the right is also isosceles with 2 congruent base angles, then
e = =
= 31
