thank you! i will probably have more

- dan815

|dw:1371012630970:dw|

- dan815

maybe u shud learn how to do these urself :)

- dan815

first remember this triangles the 30 60 90 triangle

- dan815

or just solve it!

- dan815

and u know any other 30 60 90 triangle will either be equal to this or a similar triangle to this, and similiar triangles have their side proportion equal

- dan815

use SOH CAH TOA

- anonymous

idk what that is, im in 8th grade and homeschooled. tomorrow is my last day please explain :)

- dan815

okay first memorize, SOHCAHTOA say it out

- dan815

its the name of this extremely fat native indian lady

- dan815

she is so fat she has her but t on the moon

- dan815

SOHCAHTOA IS HER NAME

- johnweldon1993

lmao @dan815 whatever you say :P

- dan815

i am trying to create vivid imagery this will help her remember SOHCAHTOA LOL

- dan815

SHE REEKS OF STINKY CHEESE everywhere she goes

- dan815

HEY THIGHS ARE THE SIZE OF JUPITER
SOHCAHTOA

- anonymous

alright, get to the point pls

- dan815

now remember this

- Luigi0210

I wanna hear dan continue..

- dan815

the first Letter of each syllable is the sin or cos or tan

- johnweldon1993

Lol okay okay Dan enough imagery XD
SOH CAH TOA
it stand for
\[\sin = \frac{ Opposite }{ Hypotenuse }\]
\[\cos = \frac{ Adjacent }{ Hypotenuse }\]
\[\tan = \frac{ Opposite }{ Adjacent }\]

- dan815

O = opposite side, H = hypotenuse and, A = adj side

- dan815

adjesecent side is the side that it is connected to but not the hypotenuse

- anonymous

i know what the hypotenuse is i get confused w opposite and adjacent.

- johnweldon1993

|dw:1371013268194:dw|
This is your triangle.....The hypotenuse is the Longest side (14)
Opposite....is the side directly across the angle
Adjacent...is the side (not the hypotenuse) that touches the angle

- johnweldon1993

|dw:1371013358136:dw|

- johnweldon1993

So since Sin = opposite / hypotenuse
What is your sin = to ...?

- anonymous

9/25?

- johnweldon1993

Where did that 25 come from?
Also, look above as I have labeled each side of your triangle...
Sin = Opposite sides / Hypotenuse side
so *for this one* it would be
Sin = 5 / 14 right?

- anonymous

i divided 5 by 14 and got .36 and turned it into a fraction

- johnweldon1993

Oh, no you don't actually divide them...you just use the labels...see how your answer choices are
sin = 5/14 etc....they got this just from taking what the side length equals....no actual math is done here

- johnweldon1993

So since....now we know that we only look at the labels of the side lengths for these...
and we know that sin = 5 / 14
cos = adjacent side / hypotenuse
so
cos = ...?

- anonymous

9/14?

- johnweldon1993

Perfect! :)
so now just tan is left
remember Tan = Opposite / Adjacent so
Tan = ...?

- anonymous

5/9 wow thats so easy. i feel stupid now lol

- johnweldon1993

Haha don't feel stupid...You hadn't learned it yet....and now that you know it....You can apply it to questions you come across in your future :) Great job!

- anonymous

how do you find a angle on a right triangle? with the sides 36, 48, and 60 is the hypotenuse

- johnweldon1993

Solving for the actual angle?

- dan815

use SOH CAH TOA

- anonymous

yeah

- johnweldon1993

For that you would use the inverse trig functions

- johnweldon1993

We use
arcsin
arccos
and
arctan
to solve for angles...when sides are known

plz watch some khan academy

- dan815

we can help u on problems if ur stuck but this is a very hard place to learn fundamental concepts
