Answer:

DB = 20 cm

Step-by-step explanation:

<u>Given:</u>

║AB = 12 cm (represented by '<em>a</em>' leg)

║AD = 16 cm (represented by '<em>b</em>' leg)

║DB =  x cm (hypotenuse represented by '<em>c</em>' leg)

<u>These formulas are used to solve for a missing side length:</u>

<em>║a</em> = \sqrt{(c^2 - b^2)}

<em>║b</em> = \sqrt{(c^2 - a^2)}

<em>║c</em> = \sqrt{(a^2 + b^2)}

<u>Because we are solving for side length </u><em><u>c</u></em><u>, we will be using the third formula.</u>

<em>║c</em> = \sqrt{(a^2 + b^2)}

<em>║c</em> = \sqrt{(12^2 + 16^2)}

<em>║c</em> = \sqrt{(144 + 256)}

<em>║c</em> = \sqrt{400}

<em>║c</em> = 20

<u>Therefore, the value for side length DB should be:</u>

║DB = 20 cm

A number k is greater than 3. Which of the following is true about 승 ? 1 It is between 3 3 It is equal to 1 It is greater than 1
Alekssandra [29.7K]

If the number k is greater than 3, we have the following inequality:

k>3

In order to evaluate k/3, let's divide the inequality by 3:

\begin{gathered} k>3 \\ \frac{k}{3}>\frac{3}{3} \\ \frac{k}{3}>1 \end{gathered}

So the expression k/3 is greater than 1, therefore the correct option is D.

Solve the following equations x1/3=2 <br> Y-2=9<br> (2s)1/2=9<br> 2n-1=16
Nookie1986 [14]

x \times  \frac{1}{3}  = 2 \\  =  > x = 2 \times 3 \\  =  > x = 6

y - 2 = 9 \\  =  > y = 9 + 2 = 11

(2s) \frac{1}{2}  = 9 \\  =  > s = 9

2n - 1 = 16 \\  =  > 2n = 16 + 1 \\  =  > 2n = 17 \\  =  > n =  \frac{17}{2}  = 8.5

<h3>The answers are :</h3><h3>x = 6</h3><h3>y = 11</h3><h3>s = 9</h3><h3>n = 8.5</h3><h3>Hope it helps!</h3><h3 />
