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

Answer:
The solution is n=1
Step-by-step explanation:
I hope you mean
4/5n-3/5=1/5n
if so then here's the solution
5n×4/5n-3/5×5n=1/5n×5n
4-3n=1
4-1=3n
3n=3
n=1
Answer:
n = 15
Step-by-step explanation:
6(1+n)=8n-3(n-7)
Distribute
6 +6n = 8n -3n +21
Combine like terms
6+6n = 5n +21
Subtract 5n from each side
6+6n-5n = 5n-5n +21
6 +n = 21
Subtract 6 from each side
6-6+n = 21-6
n = 15
