Question

How to do this, please explain with steps ASAP

Answer 1

e = 31

Explanation:

The triangle on the left has 2 congruent sides , so is isosceles with 2 congruent base angles of size

`(180-56)/(2)` =
`(124)/(2)` = 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 =
`(180-118)/(2)` =
`(62)/(2)` = 31
