Question

Can someone help me ?

Answer 1

Explanation:

a² + b² = c² (pythagorean theorem formula)

let's take 18 as a and 24 as b

So, you'll write it as

18² + 24² = c²

324 + 576 = 900²

c² =810000

c=
`\sqrt810000` = 900

c=900ft

Answer 2

Alright so A triangles perimeter is always going to be 90°

So for #1 You would add 18+24= 42 then subtract 42 from 90. 90-42=48. So for the first equation the side would be 48ft.

And for #2 You add 41+40= 81 then subtract 81 from 90 90-81=9 so the answer to the second equation would be 9 ft.

Hope this helps! :)
