that triangle is wrong

rancid sage
#

what ?

elder shard
#

its not possible to draw a triangle like that

rancid sage
#

w8 i got the right one

elder shard
#

because pythagoras theorem isn't true here

#

1^2+7^2=50
which is not equal to 5^2=25

rancid sage
#

thats the right numbers the green

elder shard
#

,w sqrt(6.348^2+4.761^2)

well not so much

elder shard
rancid sage
#

yes sir

elder shard
#

so here sin x =4.761/7.935

#

where x is the angle you want to find

#

and after that you may have to use a calculator

#

you want to find the green angle?

rancid sage
#

yeah

#

for the θ i have the formulas but for the green i dont know how

elder shard
#

opposite side is the side which is not one of the arms of the angle

rancid sage
#

so ?

elder shard
rancid sage
#

yes

elder shard
rancid sage
#

yes

#

so whats the formulas fro the green

#

tan^-1 opostie / hypotinousa ?

elder shard
rancid sage
#

what if i dont know θ

elder shard
#

it would be $\sin^{-1}\left(\frac{opposite}{hypotenuse}\right)$

rancid sage
