Ahhh solving triangles. You get one angle and one side, figure out the rest.
Once you get the hang of it, it’s quite fun. You’re given a triangle like this
To start, label the sides and list what you need to find.
Find everything that is missing (aka the stuff you just listed). We’ll start with angle F here. Since we know angle E is 90°, angle D is 50° and that the sum of the angles in a triangle must be 180°, we can just do 180-(90+50) to find angle F.
We can solve side EF and DE with the information we now have and SOH CAH TOA like so:
