ok so i understand the  a² + b² = c² thing a little better when i come to two numbers like 8²+10²... but what do you do if you only have 1 number to work with? Or like a number and the degrees of an angle?
       
        l  =                             
        l   =                           
        l       =   8       
     X l         =                                       
        l            =
        l               =
        l_                 =                                                   
        l_l______ 20  _=
              Y                       <------ Like here. Btw thats 20 degrees. In this situation im supposed to be finding both X and Y and rounding them to the nearest 10th. And like my first question its multiple choice and none of my ansers match up. -_-  the options are: 2.7, 2.9 and 7.5.

k i have another one only this time its a rectangular solid.
The given is that l=8, W=4 and H= 2. I need to find the diagonal... which in this case is d. and the answer is written as:
d=   √ then the answer.

oh and P.S thankyouX10000 devante'! smile

ok so im in geometry but my teacher thought we could handle some "basic" trigg problems and im hoplessly lost!                   
       
        l  =                              I need to find both Z and Y. i thought i new what i was doing however it is a multiple choice problem
        l Y  =                            and all the answers i came up with were not the choices. My choices are 37 39 and 51.
        l       =   X       <------- this is looks similar to the one im doing (hope it helps) so you can see that both Y and Z are on the 
    10 l         =                     on the inside. Im really stumped and i drag at math so any help is REALLY appreciated!                     
        l            =
        l               =
        l_                 =                                                   
        l_l________Z_=
                 8
