Basic Physics HW help (URGENT)

hey guys. i would like some help on these couple of problems.

i solved #1 , the answer is 26.24 i think.
for #5 a) the answer is 269.38.

Can you give me some tips for 2,6,7,8 ? I need some help on those >< please its urgent.,



THANKS in advance

Your answer to question #1 is correct.
Did you attempt question #2? I'd like to compare answers.

i didnt get an answer for #2 (not a right one at least, i checked)

What did you get?

i plugged it into the slope formula (y2-y1/x2-x1)
and that's 9.2--10/-10-9.2 but I am not sure if its correct

The question asked for the answer in degrees.
hmmm... I suppose the slope can be converted into degrees, but it has been 23 years since I've studied my trigonometric identities.

I think it would be easier to just draw a triangle and figure out the angle using the proper trigonometric function based on whichever two sides you pick.
