Answer:
The two numbers are -365 and -1825.
Step-by-step explanation:
5x=y
x-y=1460
--------------
x-5x=1460
-4x=1460
x=1460/-4
x=-365
-365-y=1460
y=-365-1460=-1825
I'm assuming that you mean

because if you meant

then u would simplify and you couldn't make it the subject.
Under this assumption, we start with

We multiply both sides by 

We expand the left hand side:

We move all terms involving u to the left and all terms not involving u to the right:

We factor u on the left hand side:

We divide both sides by 

When we choose to do cosine we do adjacent/hypotenuse so it would be...
Cos(32)= x/23
Than solve for x
X= 19.18 o 19.2
