Answer:
Step-by-step explanation:
<h2>
1) </h2>
scale is 1 inch=9 feet
4 inches*9= 36 feet
10 inches*9=90feet
<em><u>it is 36 feet by 90 feet</u></em>
<h2><em><u>
2)</u></em></h2>
scale is 1 inch=5 feet
4 inches*5=20 feet
<em><u>it is 20 feet</u></em>
<h2>
3)</h2>
scale is 1:12
14 inches*12=168
it is 168
The smallest side is HI because it’s opposite to the smallest angle
Pythagorean theorem : a^2 + b^2 = c^2
using 3,4,5
3^2 + 4^2 = 5^2
9 + 16 = 25
25 = 25 (correct)
using 8,15,17
8^2 + 15^2 = 17^2
64 + 225 = 289
289 = 289 (correct)
they are Pythagorean triplets because they satisfy the Pythagorean theorem
