R^2 = P^2 + Q^2 - 2PQ*cosθ. 465^2 = P^302 + Q^237 - 2(302)(237)*cosθ is it like that? can I also use this formula:

is it... 294.5 = l + 2b 72 = w + 2b

but I am not finding the length, arent i? I'm supposed to find the angle. I thought that equation above is for finding lengths. opposite side of angle 0 would be c, and other two sides would be a and b

So if A is (0,0) then... B = (96, 0) E = (299, 0 ) G = (102, -95) H = (204, -95) rite? and then I find the slope for line BH and GE which is y2 - y1 / x2 - x1?

294.5 = n ?

can you just give me the answer? i know that's probably the right way to learn in ur opinion, but hear me out. if you give me the answer then i can see how you got there by going backwards. i think that'd be better because i really can't figure this out and I'm not really understanding you :(

huh? I don't get it. :( so I have 10602 as the area, and now I need the legnth and width of it. 10602 = L x W how do I get the length & width when i have the areA?

10602? i divided the total area by 2.

i got the cosine law for finding angles its: cosA = b2 + c2 - a2 and divide all of that by 2bc

i still don't get it. :( i only got the total area which is 21204 inches. so you're saying its the same? so the logo's area is 21204 inches as well? ah damn i suck at this...lol.

well there weren't any measurements given to the logo, so how would i go about finding its area? as far as i know, the measurements from the mat rectangle have to do with something with its area, right? i can't seem to figure it out though. =\

it must be the cosine law, right? how do i go about finding the angle using the cosine law?

i don't know what to do :( how am i to find the uniform width of the boundary??
