Question

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

Answer 1

first of all what is the " i never memorized that

Answer 2

the star is degrees *

Answer 3

the " is inches

Answer 4

thank you

Answer 5

yeah, so we have

Answer 6

area = width times length

so we need to find length

what trig function could we use that would be opposite and adjacent ?

Answer 7

TOA

Answer 8

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)

Answer 9

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

Answer 10

? = 25 tan(38)

plug in 25 times tan(38)

Answer 11

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

Answer 12

19.53 is correct :)

Answer 13

YAY

Answer 14

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

Answer 15

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