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> = 
<em>║b</em> = 
<em>║c</em> = 
<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> = 
<em>║c</em> = 
<em>║c</em> = 
<em>║c</em> = 
<em>║c</em> = 20
<u>Therefore, the value for side length DB should be:</u>
║DB = 20 cm
