Answer:
Step-by-step explanation:
Given
Shape: Trapezoid
Required
Determine the length of the second parallel side
The area of a trapezoid is:
Substitute values for Area, Height and Side1
Multiply both sides by 2
Divide both sides by 18
Hence;
<em>The length of the second parallel side is 17cm</em>
For the answer to the question above, I'll show my solution on how you can solve your problem.
AC² + BC² = AB²
<span>5² + 12² = AB² </span>
<span>25 + 144 = AB² </span>
<span>169 = AB² </span>
<span>13 = AB </span>
<span>Triangle ABC is proportional to triangle ADB. </span>
<span><u>AC </u>= <u>AB </u></span>
<span>AB AD </span>
<span><u>5</u> = <u>13 </u></span>
<span>13 AD </span>
<span>5AD = 169 </span>
<span>AD = 169/5 </span>
<span>AD = 33.8 </span>
<span>AD = AC + CD </span>
<span>33.8 = 5 + CD
</span>So the answer is
<span>CD = 28.8 </span>
