Question

someone help me understand this :(

Answer 1

tangent of any angle of a right angled triangle = height of that triangle/base of that triangle

Answer 2

for your diagram height = 27500
base = 5000

Answer 3

yes i got that. i just dont understand the last step :( how did they get that answer?

Answer 4

im using that as an example for a question my test i just got so confused at the last part

Answer 5

on my**

Answer 6

That is where you take the inverse tangent function of that whole expression

\[\large tan(x) = 5.5 \rightarrow x = tan^{-1}(5.5)\]

Answer 7

ohh okay. can i put the question from my test on here and ill walk through the steps and you tell me if im the right track or not?

Answer 8

It will work like that with all your trig functions

If \(\large sin(x) = \text{something}\rightarrow x = \sin^{-1}(\text{something})\)
If \(\large cos(x) = \text{something}\rightarrow x = \cos^{-1}(\text{something})\)
If \(\large tan(x) = \text{something}\rightarrow x = \tan^{-1}(\text{something})\)

Answer 9

And yeah of course!

Answer 10

so i used sin for this one

Answer 11

Correct

Answer 12

and i got b

Answer 13

And you would be correct again :)

Answer 14

yes!! thank you so much :D

Answer 15

Not a problem! Good luck on the rest of your test :D
