Could someone please explain how to get the answer?
MaRussiya [10]

the missing side of the right triangle is 10.568

<h3>Pythagorean theorem formula</h3>

a² + b² = c²

<em>Which c is the hypotenuse part of triangle.</em>

<h3>Known that </h3>

a = 5.2

b = 9.2

c = ...?

<em>so</em><em> </em><em>the</em><em> </em><em>missing</em><em> </em><em>part</em><em> </em><em>is</em><em> </em><em>c</em><em>.</em>

<h3>Way to calculate</h3>

a² + b² = c²

5.2² + 9.2² = c²

111.8 = c²

c = √111.8

c = 10.568
