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!
