Answer:

<h2>x = 4.1 cm</h2>

Step-by-step explanation:

Use the Pythagorean theorem:

leg^2+leg^2=hypotenuse^2

We have

leg=x,\ leg=15.6cm:2=7.8cm,\ hypotenuse=8.8cm

Substitute:

x^2+7.8^2=8.8^2

x^2+60.84=77.44          <em>subtract 60.84 from both sides</em>

x^2=16.6\to x=\sqrt{16.6}\\\\x\approx4.1\ cm
