The correct question is
Given that sinx=3/5 where x is an acute angle, what is cosx and tanx<span>?
we know that
</span>since x is acute 0<x<<span>π/2
</span><span>then the trigonometric rations will be positive</span>
sin ²x+cos²x=1------------> cos²x=1-sin²x-------> cos²x=1-(3/5)²----> 1-(9/25)
cos²x=16/25----------> cos x=4/5
the answer part A) is
cos x=4/5
tan x=sin x/cos x
so
tan x=(3/5)/(4/5)---------> tan x=3/4
the answer part B) is
tan x=3/4
M < 2 = 90 degrees Answer
The answer is the last option
Which is (49x-16)^2
Answer:
All of them are rational except for 0.0100100010001, root50, and pi
rational = no forever decimal these are the ones that arent rational
Hope this helps plz hit the crown :D
