Fun with Triangles - SAS

[Acorn]

The next Triangle challenge extends the https://www.talkgraphics.com/showthr...Triangles-S90S one.

Take the same Triangle (B318px/H412px) [S90S].

Now instead of the two lengths being at an angle of 90°, I want the simplest means to change this interior angle to one of 142° [S142S]
If you are keen, produce a second triangle with an interior angle of 17° as well. [S17S]
