Question

I need help can someone help?

Answer 1

Your answer is
`√(184)` or 13.5646599663...

Explanation:

`A^(2) +B^(2) =C^(2) \\A^(2) +21^(2) = 25^(2) \\A^(2) = 25^(2) - 21^(2) \\A^(2) = 625-441\\A^(2) = 184\\A = √(184)`

Hope this helps!

Answer 2

Explanation:

Using Pythagoras theorem,

Let the ratio of the sides be x

B²=H²-P²

B²= (25x)²-(21x)²

B²=625x²-441x²

B²=184x²

B=13.56x.

hope this helps you.
