Given the diagram below, what is cos(45")?<br> 45° 6 <br> A. √2<br> B. 6/√2<br> C. 1/√2<br> D. 3√2
Gnesinka [82]
C. 1/root2

Based on the information, the hypotenuse will be 6root2 because it is a 45, 45, 90 triangle. The two legs will be 6. Using SOH CAH TOA, we know that for cosine, it will be adjacent/hypotenuse. The adjacent side is 6 and the hypotenuse is 6root2. The result will be (6)/(6root2). After simplifying, we get
1/root2.

ludmilkaskok [199]

The algebraic representation of the statement is x + x² - yz = 0

<h3>What are algebraic expressions?</h3>

Algebraic expressions brings the idea of creating or expressing numbers using letters or alphabets without specifying their actual values.

From the information given , we have that;

  • sum of x and it's square = x + x²
  • Equal to y × z

Now, let's equate the expressions;

x + x² = y × z

x + x ² = yz

Let's make into quadratic form

x + x² - yz = 0

Thus, the algebraic representation of the statement is x + x² - yz = 0
