How to use tangent to find the missing leg of a triangle
👉 Learn how to find a missing side length of a right triangle. A right triangle is a triangle that has 90 degrees as one of its angles. The trigonometric identities of right triangles give us the relationship between the angles of a right triangle and the side lengths of the right triangle. These trigonometric identities, commonly called SOHCAHTOA, are: sin x = opposite / hypothenuse; cos x = adjacent / hypothenuse and tan x = opposite / adjacent. These identities enable us to find a missing side length of a right triangle given one of the side lengths and one of the other angles of the right triangle.

Thanks man!! My teacher doesn't TEACH, he shows us notes and expects is to know what we're doing. This helps a ton 😊

This is single-handedly getting me through Geometry, you explained it so well!

Bruh I know this is from like 6 years ago but it actually helps man
You are a great help dude, I like your teaching style. The way you bust out your students is hilarious
Thank you! This helps a lot!
Thankyou Brian 🙂 this really helped, I’m currently doing a biology diploma and trigonometry is part of my course, I think it is my weakest area atm but I’m determined to get it lol
Thanks a ton! Your a lifesaver
It’s so cool to actually learn stuff like this in year 8. I’m not gonna get it perfect, but I like to learn stuff.
Thank you It's been 3 hours since I've started my trigonometry homework (distance learning) and I needed this ^-^
This helped me so much Thank you
what I would do to make this man my teacher. he's the only reason I'm passing math
Super helpful thank you!
I'm impressed, you are a very good teacher.
Thanks so much...my teacher explains this stuff to me so bluntly
thanks so much I was absent when my teacher explained this you have been a big help.
This man is a legend
thank you for the help
thanks man this helped a lot haven't done trig since grade 9 almost 4 years I was so lost.
this really helps!!

Thanks your videos are great
U explain so so so good the best video to find inverse trigonometry
It's amazing i would have been bored in this class. Yet i end up here on KZread because this is exactly how to measure a dovetail slot with some known sized dowel pins. Pretty cool to use this stuff in real world problems.
Boom quick maths
your honestly just so amazing omggggggg thank you so much :DDDDDDDDD
I have to do this in a geometry book, and they never even mentioned tangent. Thanks, Brian!
This guy has carried my grade this year bc my teacher isn’t very good at teaching lol

im learning more from a 5 min youtube than 1 hour of class
THANKS
Does this work for other angles on the same triangle to find another side length?
Ngl I already learned this but my teacher did like a throwback assignment and ur video helped me cuz I completely forgot how to do it
When do you if your going to multiply or divide the Tan,Cos, or Sine?
Math is beautiful!

Yes, but 3.26 what? What units? If X is the height of a tree for example, what are the units of height? Thx.
@enzoqueijao
3 жыл бұрын
Since it's a theoretical maths exercise, the unit of measurement doesn't matter, just the numbers. If you were trying to find the height of a tree, then it'd depend of the length of the adjacent side. If it was 7 meters, then the opposite would be 3.26 meters
Hello, love your videos but im still confused on my homework. the answers time out after 3 tries and im on my last attempt here. THe first two attempts they got really big numbers like 220 and 105 for the opposite side but when i do it i only get 11.55. my angle is 58.8 and my adjacent is 127 m.
I’m getting a huge number like 3.960.
I always watch your videos when my teacher confuses me 😂
This is the closest I've been to being in class this school year 😫😥😭
I can see why he has so many subs
i have a IGSCE maths test tomorrrow
Hey teach can you tell the students in my air pods to be quiet I can’t hear the lesson
