can someone me with a step by step of this problem ? i'll seriously appreciate it, and you so so so much in
don't answer if you're ! i need actual , don't just take my points. : c

For this one, you have to use the 45 45 90 rule. It would take me forever to write all of it on the computer so there is a video on Khan Academy 'Special Right Triangles intro (part 1) (video)' and 'Special Right Triangles Proof (part 2) (video)'. Also there is another video that will really help you that is called 'Geometry: Using the 45 45 90 Triangle Theorem'. These are all on YouTube. These types of videos almost always help me and I hope they help you too.

Hope This Helps and God Bless!
