MA Delta Math Tutorial for Ch 8 Quiz

Hey, real quick, guys. You're gonna watch me take part of the chapter 8 quiz just so you can see it happening. So hold on, here we go. I've got a white board right here, marker. You know. Ready to write anything down if I need to. Okay, so let me get into this. Pythagorean theorem level one, just showing you how to do this. Okay, so you can see that if I don't know how to do this exact thing, I can show an example. So they gave me an example, my legs are what and what? My hypotenuse, right? So plug in and solve. All right, and that's if you didn't recognize that that's actually a Pythagorean triple because those are all integers answers. All integers there there and there. So there's a Pythagorean triple happening. Okay? Now I go back to the original problem. You can see as many examples as you want to. But here we go. Okay. Not a Pythagorean trouble. So what I'll do here, just so you can see what I'm trying to do and then typing my answer is my whiteboard. There we are. So a squared plus B squared equals C squared. My four and one R actually legs. And C is what I'm trying to find this time. There we go. So you can still see. Okay, so one plus 16 equals C squared. So 17 equals C squared. So I take the square root of both sides. So that I can cancel that squared, and I get C equals radical 17. So I head down here to the radical sign, and then type 17. It's a bit my answer, and yes. So there I go. Okay? Oh, please don't take my watch there, sweetheart. Closer. Say hi. Okay, so if I want, I can go back here, and I can do whichever section I want to do at whatever time, okay? So now I can go to the identifying the trick. Section, because I thought this was really cool. You can take my watch, go ahead. What do you want? Can you wait one minute? Can you write a problem down for me? Or use my spinner? Here we go. Use this better. There you go. Thank you. So you don't like the spinner since when? All right, so ready? Watch. So here we go. We're looking for the sign of B, go to your angle in question B, sine is opposite over hypotenuse. So 16 over 34, and you keep going. Sine of a so a right here. So sine is opposite over hypotenuse. Tangent a here is tangent tangent is opposite over adjacent. And I just keep going. Tangent B okay, here we go. So tangent is opposite over adjacent. Tangent a opposite over adjacent. Oh, sorry, I can't see. There we go. I got that one. Excuse me. So. Since I got that one wrong, I think he is in the way down here. I couldn't see it. I would restart. And go again, okay? Hold on, there's something on my back. So just so you can see how that goes. All right guys, hopefully now. Hopefully that helps out a little bit. I shall see all soon.
