Question

The diagram below shows the map of a mine.

Answer 1

How deep is the mine shaft?
Answer
6 tan 20˚
6 cos 20˚

Answer 2

other answer choices are: 6/sin20 degrees
6/tan 20 degrees

Answer 3

what is tangent

Answer 4

um...Tangent Function:
tan(θ) = Opposite / Adjacent

Answer 5

alright so looking at your picture what are your givens and your x

Answer 6

6km 20 degrees

Answer 7

x idk

Answer 8

so you have

\[\theta = 20\]
\[A=adjacent=6\]

Answer 9

and what are you trying to find?

Answer 10

BC

Answer 11

the opposite I think

Answer 12

yes your opposite angle is always opposite of your angle

Answer 13

if you name the opposite angle x and put it into your tangent equation you should get...

Answer 14

D I think

Answer 15

70 degree

Answer 16

not the answer choice

Answer 17

using tan(theta)=X/a

Answer 18

70 is not correct

Answer 19

but sin formula is also applicable ... just tell the unknown angle

Answer 20

I'm confused :?

Answer 21

6/tan 20 degrees?

Answer 22

known:
\[\theta=20\]
\[o=?=x\]
\[a=6\]

given:
\[\tan(\theta)=\frac{o}{a}\]

Answer 23

yeah

Answer 24

alright so plug everything in you should get

\[\tan(20)=\frac{x}{6}\]

Answer 25

now to get x by itself you'd need to...

Answer 26

aha!

Answer 27

its 6 tan 20˚

Answer 28

yes

Answer 29

pls bare with my stupidity

Answer 30

OMG I got it?!

Answer 31

thanks! :D

Answer 32

yap you did it

Answer 33

i'm assuming that 6tan(20)=70 which is where annas got his answer

Answer 34

lol I expected him to say WRONG lol

Answer 35

Thanks guys!

Answer 36

no i was using a/sinA = c/sinC and answers are same i was just telling about the unknown angle by 180-(90+20)

Answer 37

answer is 2.1 if u simplify it ...
