OpenStudy (anonymous):
find the angle
find the sides
OpenStudy (anonymous):
okay hold on
OpenStudy (anonymous):

Okay I won't interrupt but this is so easy
OpenStudy (anonymous):
no its fine if you can help please do! @Luis_Rivera
OpenStudy (anonymous):
yes
here
the 2 angles are equal
so trigonomatric values wil be same
so cos =21/29
and for other angle cos = 20/b
OpenStudy (anonymous):
so 21/29 = 20/b
solve for b
OpenStudy (anonymous):
okay, I dont see that for the answers ^ would it just be 20*29 then that divided by 21? @aajugdar

OpenStudy (anonymous):
okay so then what?
OpenStudy (anonymous):

OpenStudy (anonymous):

did you get b=28
OpenStudy (anonymous):
what are the answers
OpenStudy (anonymous):
a= 400/21, b= 580/21
a= 400/21, b= 20/21
a=580/21, b=29/21
a= 20/21, b= 580/21
OpenStudy (anonymous):
dude no need for Pythagoras
OpenStudy (anonymous):
okay...

yeah i am sorry i still dont get it..i
OpenStudy (anonymous):
like i read the link but how should I go about setting it up?
OpenStudy (anonymous):
Where there are the lengths of the sides in the pc, substitutes the number you have.
gotta go
OpenStudy (anonymous):
okay thanks
