Question

Pleae help thanks a bunch

Answer 1

Hello!

You use the Pythagorean theorem to solve this


`a^(2) + b^(2) = c^(2)`

Put in the values it tells you to


`a^(2) + 4.4^(2) = 5.5^(2)`

Square the numbers


`a^(2) + 19.36 = 30.25`

Subtract 19.36 from both sides


`a^(2) = 10.89`

Take the square root of both sides

a = 3.3

The answer is 3.3

Hope this helps!
