Question

Solving one triangle using two?

Answer 1

so you can use the pythagorean to find either a or b



then proceed from there

Answer 2

I know a^2+b^2=c^2
But.. How do you do about only knowing c^2?

They make sure to only give you 2 details about both triangles, so you can't solve one and figure out the other. Gah. I just need a hand to move forward. ><"

Answer 3

What class is this for btw?

Answer 4

Geometry ><"

Answer 5

I don't want the actual answer, I just need a hand going about getting another number so I can solve it.
I didn't post what A B C or D was for a reason..!

Answer 6

you're rigth about that, i didn't notice.. maybe you can use some sort of ratio? let me seee

Answer 7

how about if u post A , B C or D
bec sometimes good to solve a question backwards :D :D
js

Answer 8

\(tan(\theta)=\dfrac{12}{x}\)

\(tan(90-\theta)=\dfrac{21}{x}\)

maybe from here make some substitutions?

Answer 9

I would rather know how to work about doing it without going backward, for the sake of possibly not having the answers next time.

Answer 10

nobody is going to give u a direct answer
i said that for some reason
it's a math
we have to play with numbers
i was saying some time it helps
anyways good luck
thanks

Need more guidance, just let me know

Answer 12
