Complete the following item. Consult the table above to find the cosine number. Find A to the nearest degree. A = ? degrees.
seems like your matching numbers to angles according to what i can read from this
good, now how do we define cosine?
the ratio of the side adjacent to the angle over the hypotenuse.
good, which value would you say is the side and which is the hypot in this pic?
267 is the side and 391 is the hypot
good, and when we divide 267 by 391 we get a value of about .6828 that we need to find on a table of cosines
do you have the table that was spoken of in the post?
no but hold on
here it is
look at the columns that are labeled as "cosine" and find the values that our 6828 fits inbetween
51
hmmm, i would say it fits better between 46 and 47. wouldnt you?
6947 6828 6820 46 our# 47
oh yea ur right, don't know what i was thinkin
our# is closer to 47 than 46, so id approx it to 47
ok
post up another one and see who bites, i have to go home soon
good luck ;)
thankyou so much for ur help
