Step-by-step explanation:
<h2>3(100)2 + 17(100) - 20</h2>
3(10000) + 1700 - 20
30000 + 1700 - 20

Hi Vance :)
a=leg unknow
b=leg
c=hypotenuse
a²+b²=c²
a²=c²-b²
a²=145² - 144²
a²=21,025 - 20,736
a²=289
a=√289
a=17
unknow leg = 17 units

The numbers are 3, 7, and 11.
No. The definition of an acute triangle is, all three angles must be less than 90°.
I believe the answer is 12
