Answer 3

http://www.mathsteacher.com.au/year7/ch12_length/07_triangle/triangle.htm look at this then i'll help you out just help you get an understanding

Translated meaning is the long side squared equals the sum of the two other sides squared. use that to find the length of the side

Answer 13

but i dont understand cuz 30 is the area so its not a leg

Answer 14

Answer 16

\[\sqrt{30^2 + 12^2 =32.31099}\]

Answer 17

now that you have all the sides of the triangle (30,12,32.31099) use this formula (a+b+c= the perimeter
