Math Is Fun Forum

it would be a 100 ft or am i getting the question wrong?

soo the first problem the triangle is an iscoseles triangle? cause both sides equal the same right? or not? and do the sin and tan and cos have diffrent purposes or can you use them all?

I like the first one and the third one xD

i did for the tan 4/3 and then clicked tan-¹

oh so the sine is equal to the tan
let me see about the cos

huh what do you mean wait where did he go?

soo 3/5 = 36.87°

am i right i used sin can you explain to me why i picked sin to get a?

is it the "sin" with the negative 1 exponent?

hi im back and for the triangle question im guessing you have to use cosine.. right? and im guessing the angle is umm lets see uhh im confused i did the 3/5 and i got 0.6 but that definattly isnt the answer cause the angle looks way bigger helpz D:

what triangle and gtg now ill be back in the afternoon bye

i havent learned it yet but i saw it somewhere i think it was sin = opp/hyp cos = adj/hyp and tan = opp/adj right?

ok ive only read the example one and it shows you how you find the sin tan and cos but why do you use them and when? im sorry if theyve the tutorial has already answered my question but im kinda of a bad reader.
