Find the values of x and y.

@jhonyy9

jhonyy9 (jhonyy9):

from this little triangle how you can finding the y value ?

OpenStudy (montsechamorro):

Pythagorean theorem

jhonyy9 (jhonyy9):

yes

OpenStudy (montsechamorro):

so it'd be x2+y2=z2

jhonyy9 (jhonyy9):

i said little triangle with y ,65 and 25

OpenStudy (montsechamorro):

ohh so

OpenStudy (montsechamorro):

wait how would i find hypotenuse

jhonyy9 (jhonyy9):

not y is the hypotenuse there - y is a leg ,65 is the hypotenuse

OpenStudy (montsechamorro):

so 25^2+y^2=65

OpenStudy (montsechamorro):

625+y^2=4,225

jhonyy9 (jhonyy9):

but there above you missed the exponent of 65

OpenStudy (montsechamorro):

yes sorry

OpenStudy (montsechamorro):

65^2

OpenStudy (montsechamorro):

25^2+y^2=65^2

jhonyy9 (jhonyy9):

ok. y = ?

OpenStudy (montsechamorro):

y^2=3,600

jhonyy9 (jhonyy9):

and y = ?

OpenStudy (montsechamorro):

I'm stuck :(

OpenStudy (montsechamorro):

60?

jhonyy9 (jhonyy9):

why ? y = sqrt3600 so yes perfect do you see that you know it

OpenStudy (montsechamorro):

i forgot about the square root

jhonyy9 (jhonyy9):

you need more much courage bc. you know but you dont believe in your knowladges

jhonyy9 (jhonyy9):

so you know the y and now ?

OpenStudy (montsechamorro):

so is z the hypotenuse

jhonyy9 (jhonyy9):

for this little triangle from the right part yes but you dont know again the value of x

OpenStudy (montsechamorro):

alright so do i wait on Pythagorean theorem?

jhonyy9 (jhonyy9):

in this case you not can using this theorem so in this case you need to know the theorem of amplitude from the right angle on hypotenuse in a right triangle what say ?

jhonyy9 (jhonyy9):

do you know it ?

OpenStudy (montsechamorro):

no

jhonyy9 (jhonyy9):

this say that the length of altitude squared is equal with the product of the shadows on the hypotenuse of this altitude so do you understand it ?

OpenStudy (montsechamorro):

sorta

jhonyy9 (jhonyy9):

so this mean in this case of this triangle that y^2 = 25*x ok. ?

jhonyy9 (jhonyy9):

so how fing from there the value of x ?

jhonyy9 (jhonyy9):

find - sorry

OpenStudy (montsechamorro):

i got 144 for x with a little help from my dad :D

jhonyy9 (jhonyy9):

y^2 = 3600 yes 3600 = 25x x = 3600/25 x = 144 yes this is perfect

jhonyy9 (jhonyy9):

so now you know the value of x and the value of y and you need finding the value of z yes ?

OpenStudy (montsechamorro):

I only need x and y for this problem yay!

jhonyy9 (jhonyy9):

ok i forgot it sorry so do you understand it now sure right ?

OpenStudy (montsechamorro):

Yes for the most part, I'm on to my next unit with trigonometry and I'm already lost, ill start a new question if you don't mind helping me

jhonyy9 (jhonyy9):

ok just tag me there
