Answer:
x = cos(θ)
Step-by-step explanation:
The above relation is one that is usefully committed to memory. The mnemonic SOH CAH TOA can help you remember it, along with ...
y = sin(θ)
The x-value is adjacent to the central angle; the y-value is opposite. The hypotenuse of the relevant triangle in a unit circle is 1.
The x-value is ...
x = cos(θ)
_____
These relationships are necessary to convert from rectangular to polar coordinates and vice versa. They are also helpful when working vector problems.

Ok. So, if 8 pens cost £12. Then we would divide £12 by 8. Each pen costs £1.5.
So now we are going to multiply £1.5 and 10. £1.5*10=15.
The total of 10 pens is £15.
I hope this helps, if you need any additional help, just ask. I am here to help you as needed.
The slope is 2 and the y intercept is 4
Answer: Vu is 15 years old now.
Step-by-step explanation:
Let present age of WU be x.
Then, the present age of Vu = 3x
Also, After 25 years
Age of Wu = x+25
According to the question:
Present age of Vu = 3(5) = 15
Hence, Vu is 15 years old now.
