Question

solve for x using sin, cos, tan

Answer 1

ues Pytha goras theorem, or use trigonometric identities directly..... Say what you prefer most ?

Answer 2

\[\sin 36=\frac{ 10 }{ x }\]
\[(x*)\sin36=\frac{ 10 }{ x }(* X)\]

Answer 3

thats as far as i have gotten

Answer 4

\[X \sin 36=10\]

Answer 5

\( (x*)\sin36=\frac{ 10 }{ \cancel{x} }(* \cancel{X}) \)

Answer 6

keep going, your target is x

Answer 7

how do i get x alone

Answer 8

do i divide by sin 36?

Answer 9

yes !

Answer 10

so \[x=\frac{ 10 }{ \sin 36 }\]

Answer 11

looks perfect !

Answer 12

17.01

Answer 13

or 17 approx

Answer 14

\(17 = \color{red}{\checkmark}\)

Answer 15

im unsure sometimes on how to do some steps ^^

Answer 16

you're doing great, takes lil practice thats all :)

Answer 17

you got to

Xsin36=10

if the problem was
x*2 = 10
you would know what to do: divide both sides by 2

the reason you are unsure of what to do is you are forgetting that sin36 is just a fancy way to write down a number. You can always divide both sides by a number.
