Question #a8be9

Answer 1

`x=-43`

Explanation:

Assuming that I am interpreting the diagram correctly:
1. we have an isosceles triangle
2. divided into 2 sub-triangles by the horizontal line
3. with the horizontal line bisecting the angle through which it passes.

If these assumptions are true then the two sub-triangles are congruent (SAS), and
`2x+136=50`

`rarr 2x=50-136=-86`

`rarr x=-43`
