woah woah woah. green does not look good on her. I would say... hmmmmm...electric blue!!!! :D

Use the 2nd button in the top left and then the asin button right below it.

okay. okay. okay. i won't say "eww" -.-

I did the math and got -3

I'm all fine

$${\mathtt{0.2}}{\mathtt{\,\times\,}}{\mathtt{8}} = {\frac{{\mathtt{8}}}{{\mathtt{5}}}} = {\mathtt{1.6}}$$

$${\mathtt{0.3}}{\mathtt{\,\times\,}}{\mathtt{6.5}} = {\frac{{\mathtt{39}}}{{\mathtt{20}}}} = {\mathtt{1.95}}$$

$${\mathtt{0.4}}{\mathtt{\,\times\,}}{\mathtt{80}} = {\mathtt{32}}$$

$${\mathtt{0.25}}{\mathtt{\,\times\,}}{\mathtt{23}} = {\frac{{\mathtt{23}}}{{\mathtt{4}}}} = {\mathtt{5.75}}$$

$${\mathtt{0.15}}{\mathtt{\,\times\,}}{\mathtt{11}} = {\frac{{\mathtt{33}}}{{\mathtt{20}}}} = {\mathtt{1.65}}$$

for the free body digram for B 

why Tsin40 directid to the left ? 

And maybe the calc is contagious....because that is where I got the answer...

Oh no!  I'm contagious!  At least you have a sense of humor......

4*4=16

Another way to write this is:

4+4+4+4=16

happy7,

The asker wants to know how to find (a) (what does a =).

Where is that answer, happy?

1/2 of 1/3 is 1/6

So 1/6 didn't fail

i can post more if you guys would like

they want the normal force right  ? 

You need to click 2nd, then sin().

It will come up as asin(), but it's the same thing.

Alternatively, you can type sin^-1() or asin()
