Answer:
Step-by-step explanation:
The diagram is given to you below. I could not change <C so that it was theta. So C = theta.
So C is the reference angle. Call it theta when you think of it. The diagram shows you how cos(C) must be set up.
The adjacent side is 7
The hypotenuse is 18
theta = C = cos-1(7/18) = 67.11
To the nearest degree 67.11 = 67
The expression given in the question is expressed as a power is x^10
According to the law of indices, multiplication of powers becomes addition as shown:

Given the following expressions;

This can also be expressed as:

This shows that the expression as power is x^10
