How do I solve for X? I need all the work. Cos(x)=(1/1.0545829)?

Answer 1

So, we know that Cos(x)=(1/1.0545829)
Cos(x)=0.948242191.....
So, x is an angle. Therefore,
x=Cos-1(0.948242191....)
We use Cos-1 because when it was on left side it was + and now on the other side it is -, because we are solving for x and x is an angle.
So, x = 18.5147043190....... Degrees
So, iI will round it to two decimal places.
x = 18.51 Degrees, because x is an angle.

Now if you want to check your answer...
Cos(18.51) = 0.948242191.....(which means 1/1.0545829)

So, bye you got your answer + full work.....

Answer 2

if cos(x) = 1/1.0545829, then x is simply the inverse cosine of (1/1.0545829). That's all. There's no need to try and bring in trig identities or other things to make it more complicated. It's as simple as you can really get.

You can write it as "x = cos^-1 (1/1.0545829)". Or I suppose x = sec^-1 (1.0545829). But if you want to evaluate it, you really should just grab a calculator. The answer is about 18.51 degrees.

Answer 3

you need a calculator:
use the inverse cos function on the calc.
cos^-1(1/1.0545829) = answer will appear in radians

Answer 4

apply

Cos (x) = Base/ Hypotenuse

Cos^2 (X) + Sin^2(x) = 1

and u will get the ans.

Answer 5

do you have calculator???
