In trigonometry, secant in a right triangle, is the reciprocal of the cosine of an angle symbol: sec while cosine is in a right triangle, is the ratio of the length of the side adjacent to an acute angle to the length of the hypotenuse.
The cosine of an angle is the ratio of the length of the side adjacent to the angle divided by the length of the hypotenuse of the triangle. The cosine of ∠A will be abbreviated as cos ∠A
The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x .
Answer: 7x+y+8
Step-by-step explanation:
Combining like terms is just like what it sounds. You take the like terms, or terms that have the same variables and such, and add them together.
For this problem, we can see that 12x and -5x are like terms because they both consist of a numerical coefficient and the variable x.
We can see that -3y and 4y are like terms because they both have a numerical coefficient and y for variable.
Now, we can combine like terms.
12x-3y+8-5x+4y [combine like terms]
7x+y+8
Hey there,
5x + 6 = 66
5x = 66 - 6
5x = 60
x = 60 / 5
= 12
Whenever a number crosses a equal sign it changes into its opposite - for example when 5 crosses the equal sign, it become -5.
Hope this helps :))

Answer:
Option D is the answer.
Step-by-step explanation:
As we know there are two types of muscles, Voluntary and involuntary muscles.
Voluntary muscles are the muscles which we can control while involuntary muscles can not be controlled .
Examples of involuntary muscles are Smooth muscles present in GUT, blood vessels and cardiac muscles.
Examples of voluntary muscles are skeletal muscles like facial muscles.
Therefore, Option D, making of faces involves voluntary muscle movement.
