Question

give the sine, cosine, and tangent.

Answer 1

i dont know how to figure this out.

Answer 2

would the sine be 4/3 ?

Answer 3

first we need the hypotenuse to find the trig ratios so use the pythagroean theorum to find hypotenuse

Answer 4

hypotenuse is 12. correct ?

Answer 5

and with that in mind sine = 2/3 my mistake. right?

Answer 6

nope
8^2+6^2=c^2
100=c^2
c=?

Answer 7

okay 10

Answer 8

yes now do you know the trig ratios?

Answer 9

SOH CAH TOA

Answer 10

sine = opposite / hypotenuse
cosine = adjacent / hypotenuse
tangent = opposite / adjacent

Answer 11

okay so sine = 4/5

Answer 12

yes so lets identify the opposite,adjacent,and hypotenuse of angle E
opposite=8
adjacent=6
hypotenuse=10
now just use your ratios and i will check

Answer 13

yes correct

Answer 14

cosine = 3/5

Answer 15

yes

Answer 16

tangent = 4/3

Answer 17

yes good job
but remember its sin(angle e) not just sine=

Answer 18

okay. :) so i could write it (angle E) sine = 4/5 and it would be correct? or would i have to write it sin (angle E)

Answer 19

generally its the second way

Answer 20

like for any thing it would be \[\sin (\theta)\]

Answer 21

where that symbol means theta or just any angle measure
sorta like x for angles

Answer 22

okay and i would do that for cos and tan then as well, right?

Answer 23

correct :)
