Sin and cosine of the acute angle are complementary trigonometric functions. This means that between these trigonometric functions, the rule of complementary acute angles applies: sin64° = cos(90°-64°) = cos26°
So, if we have given cos64° = cosx and we want to determine the value of the acute angle x, given the complementarity of the angles to 90 degrees, the required value of the angle x is 26°.
The answer is: x = 26°
The function of the noun is as a noun clause. "Noun clause: whoever finishes her dinner first Function of clause: subject
<h3>What is a noun clause?</h3>
A noun clause is a dependent clause that acts as a noun in a sentence. It can function as a subject, an object, a complement, or an appositive.
The noun clause in the sentence is whoever finishes her dinner first. This clause acts as the subject of the verb gets. The subject is the person or thing that performs the action or is in the state of being of the verb.
To identify the noun clause, we can ask ourselves who or what gets to serve dessert. The answer is whoever finishes her dinner first, which is the noun clause.
We can also replace the noun clause with a pronoun, such as she or they, to see if the sentence still makes sense. For example:
She gets to serve dessert.
They get to serve dessert.
These sentences are grammatically correct, although they may not convey the same meaning as the original sentence. This shows that the noun clause is functioning as a noun in the sentence."
