Answer: 4
Step-by-step explanation:
For this question, we have to divide the number 8 by 2.
8 ÷ 2 = 4
Now, we have to take the quotient, 4, and multiply it by 1.
1 x 4 = 4
The answer is 4.
We have that
tan x=5
we know that
tan x =sin x/ cos x
sin x/ cos x=5------> squaring-----> sin² x/cos² x=25
remember that
sin² x+cos² x=1-----> cos² x=1-sin² x
substitute
sin² x/[1-sin² x]=25
sin² x=25-25*sin² x
26*sin² x=25
sin² x=25/26
sin x=5/√26
cos² x=1-(5/√26)²----> 1-(25/26)----> 1/26
cos x=1/√26
the answers are
sin x=5/√26
cos x=1/√26
Answer: M=matts age

Step-by-step explanation:I am assuming you mean write an equation
Answer:
I will put this into fractions for you- I hope you meant that
Step-by-step explanation:
15x turns into 30/2x
-4y turns into -8/2x
And finally 18 turns into 36/2
So the whole equation looks like this-
30/2x-8/2x=36/2
P.S. I just multiplied everything by 2 and put 2 as the denominator
