Answer:
a = 6, b = 12, c = 6, d = 6√3
Step-by-step explanation:
The two triangles are the "special" triangles.
The 45-45-90 triangle has side lengths in the ratios 1 : 1 : √2.
The 30-60-90 triangle has side lengths in the ratios 1 : √3 : 2.
Then ...
c : a : 6√2 = 1 : 1 : √2 ⇒ c = a = 6
and ...
a : d : b = 1 : √3 : 2 ⇒ d = 6√3 and b = 12 . . . (since a=6)
The lengths are ...
a = 6, b = 12, c = 6, d = 6√3
In triangle, ABD,
AD²= AB²+BD²
AB² = AD²-BD²
AB² = 18²-9² = 324-81 = 243
AB = √243
In triangle, ABC,
AC² = AB²+BC²
AC² = (√243)²+(13)²
AC² = 243+169
AC = √412
AC = 20.29
<h2>$525</h2><h2>--------------------------</h2>
<u>Step-by-step explanation:</u>
<h3>cost price = $450</h3><h3>selling price = $975</h3>
profit = selling price - cost price
= $975 - $450

Theoretically, the answer is infinity. however, in a non perfect universe such as our own, practically the answer would be around 17ft.
It would be: 5/12 * 100 = 500/12 = 41.66%
So, your final answer is 41.66%
Hope this helps!
