Question 1027469: I have no idea what I am doing on this homework that I have. I guess I wasn't paying attention. Can someone please help? I'm in 7th grade but I'm learning 8th grade math because I'm above level. How the heck do i find an angle to a right triangle. It's missing. This homework was due a long time ago too. I think I was absent because I'm usually a really smart person. Okay so when someone responds like the angel they are, I will tell you the other problems. You know what never mind i just need the equation on how to find it. I need to find the missing lengths on the right triangle. I'm so sorry for sounding unprofessional or something but i really need to be taught this because as of now i am failing math.
thanks,
