Sir, you are great teacher Because unlike any youtube tutorial videos your voice is loud and clear, your examples are brilliant and The best of all it's completely free... Thank you so much Sir You were such a big help for me
This video is a life saver. I want to say you taught this in a much easier to understand way than my teacher did in a week. Granted, I didn't pay much attention on Sines, but I did with Cosines, and I now have a clear understanding of both. My teacher never mentioned anything about Cosines being used on SSS and SAS triangles. You have a really good way of teaching this stuff. Good job!

Mario's explanations and examples are amazing. He makes learning the material so many times easier, and the fact that he's doing this for free and out of the good of his heart is amazingly gracious. He's the math teacher we all wanted, but didn't deserve. Someone give him a cinnabon
This video is the only thing I actually learned during online school lollll
Super helpful! Needed an extra bit of review and this was perfect!
It was this easy!? Wow thank you so much, you thought me what 3years of private high school couldn't! Thank. You sosososo much
This dude taught me more in 9 mins then my teacher did in 2 weeks
Dude this helped so much I was gone the day we learned this and had no clue what was going on but after this video I’m feeling great about these problems now. Thank you so much!!!
yo just helped me past my test you are a living legend
I really frustrated with this due to taking it online, but this video has helped me understand it more thank you.
You have a great way of explaining things so that they make sense, giving the reason behind why things are being done and providing ways to memorize things in an effective way. Thank you for this gift.

hey what if you’re given a triangle without labeling sides ABC respectively and there’s a missing angle at the top?
@CookiehsAndDreams

I might be a little late on this and I don't fully understand it either, but if you have the angles of the other two sides, you should be able to just subtract those two angles from 180, you should be able to get the missing angle. I might be wrong, but I hope I could help a little!

You want to get the sinC by itself….another option is to cross multiply to get rid of the fractions. Hope that helps!

An 18m cable is connected to the top of a 14m radio mast and fastened to the ground at an angle theta to the horizontal. 1. Draw a diagram to illustrate the problem? 2. Calculate the theta in degrees correct to 2 decimal places? Post your ASAP??
I just need help with the calculator how did u get .805 I couldn’t get it
Great 👍 sir.
Hey just a little thing but maybe show us what your calculators says zoom into the calculator or show the camera it so we can see the weapons you push
How do we plug in the cosine ratio into the calculator because I keep getting larger numbers instead of 6.7 6:37
Thank you sir
thank you you helped A LOT!!! may god reward you
in 5 minutes you explained what it took my teacher like 7 weeks to even do half
At 2:36 he says that the angle is 53.6 but when I put it into the calculator I got 53.61 so wouldn’t it be 53.6? I’m so confused 😢

Wait how did you multiply by inverse of cosine with no degree measure
God bless
bro saved my ass, thank you.
what iff theres no degrees or number inside the triangle
