What is the area of a rectangle with the width of 25" and the angle between the width and the diagonal measuring 38*? @jigglypuff314 this one really confuses me

Question

elisaneedshelp · Answer

first of all what is the " i never memorized that

elisaneedshelp · Answer

thank you

jigglypuff314 · Answer

yeah, so we have |dw:1394415195635:dw|

jigglypuff314 · Answer

area = width times length

so we need to find length

what trig function could we use that would be  opposite and adjacent ?

elisaneedshelp · Answer

TOA

jigglypuff314 · Answer

yes :)
so we would use tangent

tan(angle) = (opp/adj)

angle = 38
opp = ?
adj = 25

plug in what you know
so  tan(38) = ? / 25     (multiply both sides by 25 to get ? by itself)
so  ? =  25 tan(38)

wait im confused on how to plug in the ?/25

jigglypuff314 · Answer

? = 25 tan(38)

plug in  25 times tan(38)

elisaneedshelp · Answer

Oh ok its just i get confused when they put the equation tan38=x/25 so the only thing to put in is 25xtan38 and then its 19.53

jigglypuff314 · Answer

19.53 is correct :)

YAY

elisaneedshelp · Answer

i realized that you missed a step but i think i figured it out

elisaneedshelp · Answer

cuz on a problem my teacher multiplied it by the width at the end after the angle measure so it be 25xtan38x25
