6.5

Answer 3

answers to the top
3.7
11.5
3.3
4.5

Answer 4

Ok. so which trigonometric ratio would mean the ratio of \[\frac{ 9 }{ x }\]

Answer 5

use sine theorem

Answer 6

note sin(90)=1

Answer 7

wait what lol sorry guys im not that great at this :(

Answer 8

@Missaa143 at least you are aware that there is something called sin x, cos x etc etc etc ?

Answer 9

yes

Answer 10

ok, let's consider the first one

Answer 11

use pythogorean theorem to find hypothenuse (the longest side of right triangle)

Answer 12

okay right

Answer 13

hypothenuse^2=5^2+x^2

Answer 14

hypothenuse/sin(90)=x/sin(42)

Answer 15

@Missaa143 so you know which side divided by which side is cos of any angle?

Answer 16

okay gotcha!

Answer 17

or you can go directly, x/sin(42)=5/sin(90-42)

Answer 18

7/30

Answer 19

= 0

Answer 20

u can also use Tan of 42 = x / 5.

Answer 21

true! ^

Answer 22

ill say the first one is 3.3 ?

Answer 23

\[\frac{ x }{ \sin(42) }=\frac{ 5 }{ \sin48 }\]

Answer 24

no it will be 4.5

Answer 25

Ooooo okay i get it!

Answer 26

in 2nd one you have hypotenuse = x, and base = 9.

So which trig. ratio means base/hypotenuse?

Answer 27

i think its D ?

Answer 28

I think it would be easier if you use tan(42)=x/5 => x=5tan(42)
