Yes

Answer 6

Thanks :)

Answer 7

Do you understand what to do?

Answer 8

I cant give direct answers so we have to do the work together :D

Answer 9

Alright, I thing the longest side is 10 because it says "10-inch body" I am not sure if it is the whole truck or just the load though.

Answer 10

'10-inch body' could be referring to the hypotenuse or the horizontal leg. I would think it's the hypotenuse.

Answer 11

The hypotenuse is the longest side correct?

Answer 12

Only thing it gave me is 2 angles 90 & 30. And the Hypotenuse. I am confused what to do after that.

Answer 13

and your tring to find the missing side

Answer 14

How would I do that?

Answer 15

You have the trig relation
sin30∘=10/x
Solve for x.

Answer 16

you would multiply both sides by x

Answer 17

30x=10x?

Answer 18

\[\chi \sin30= \frac{ 10 }{ x } \times x\]

Answer 19

\[x \sin 30=10\]

Answer 20

So whats your answer?
