If is a n acute angle and tanx=3 4 evaluate cosx-sinx cosx+sinx
if tanx = 3/4,
sinx = 3/5
cosx = 4/5
and go from there
the ans
If x is an acute angle and tan x = 3/4 evaluate cos x_sin x cos x+sin x
I got it
4/5-3/5 divided by 4/5+3/5
Then go from there
I can't get it
Up if x is an actue angle and tan x° 3/4 evaluate cosx - since/cosx+sinx
To evaluate cos(x) - sin(x), we need to find the values of cosine and sine for angle x.
Given that tan(x) = 3/4, we can use the identity tan(x) = sin(x) / cos(x) to find the values of sine and cosine.
Let's solve for sine and cosine:
tan(x) = sin(x) / cos(x)
3/4 = sin(x) / cos(x)
To find the values of sine and cosine, we need to find the value of x. Unfortunately, the given information is insufficient to determine the value of x because the value of tan(x) alone does not uniquely determine the value of x.
To find x, we can use the inverse tangent function (arctan) to find the angle whose tangent is 3/4:
x = arctan(3/4)
However, this will give us an angle, not a specific value for cosine and sine. Therefore, we cannot evaluate cos(x) - sin(x) accurately with the given information.
Similarly, we cannot evaluate cos(x) + sin(x) accurately without knowing the value of x.
