@darkknight

Answer 2

you are a great help btw ty

Answer 3

Try this one by yourself, see what you can getl

Answer 4

Start thinking about what trig function is going to help us in this scenario

Answer 5

Im thinking tan

Answer 6

Well yes. You have to remember that the trig function are all talking according to which angle you choose. The 2 sides are opposite and adjacent so yes it is tan.

Answer 7

Do you know how to set it up?

Answer 8

I know its the opposite over adjacent

Answer 9

but im wondering where the 43 would be

Answer 10

So this is how you set it up.
Tan(angle) = (Opposite side)/(adjacent side)
plug your values in.
then to solve for the angle
Tan^-1(Tan(angle)) = Tan^-1((opposite side)/(adjacent side))
angle = Tan^-1((opposite side)/(adjacent side))

Answer 11

You with me so far?

Answer 12

so tan (43)=(6)/(c)
I got 6.4

Answer 13

rounding to the nearest tenth u got it right! Keep it up

Answer 14

Okay now im stuck lol

Answer 15

You got the right answer.

Answer 16

Where are ou stuck

Answer 17

No just to understand I mean so it was tan because there are 2 sides that are opposite and adjacent? just so I can know in the future

Answer 18

Here: The 3 main trig functions you encounter in geometry are Sin, Cos and Tan

Sin (you use when the opposite and hypotenuse) \[\sin(\theta)=opposite/hypotenuse\]
Cos( you use when the adjacent and hypotenuse) \[\cos(\theta) = adjacent/hypotenuse\]
Tan (you use when the opposite and adjacent) \[\tan(\theta) = opposite/adjacent\]

Answer 19

So based on the sides respectively to the angle (theta) you would know which trig function to use.

Answer 20

Okay got it thanks
