Step-by-step explanation:
Answer:
tan(θ) = 0, 0.577, -0.577
Step-by-step explanation:
3tan³(θ) - tan(θ) = 0
tan(θ)(3tan²(θ) - 1) = 0
tan(θ) = 0
tan²(θ) = ⅓ tan(θ) = +/- sqrt(⅓)
tan(θ) = 0, sqrt(⅓), -sqrt(⅓)
tan(θ) = 0, 0.577, -0.577
To find θ values, domain is required
Answer:
37.8
Step-by-step explanation:
Set up a proportion using the values given in the diagram of similar triangles.
31.5/15 = x/18
Cross-multiply.
31.5(18) = 15x
Multiply.
567 = 15x
Divide both sides by 15.
37.8 = x
Evidence are simply facts to support a claim, while counterexamples are instances to show the contradictions in a claim
<em>The question is incomplete, as the required drop-down menus are missing. So, I will give a general explanation</em>
<em />
To show that a statement is true, you need evidence.
Take for instance:

The evidence that the above proof is true is by taking the <em>squares of both sides of </em>


However, a counterexample does not need a proof per se.
What a counterexample needs is just an instance or example, to show that:

An instance to prove that:
is false is:

Hence, the complete statement could be:
<em>In a direct proof, evidence is used to support a proof
. On the other hand, a counterexample is a single example that shows that a proof is false.</em>
