The length of the missing side of the triangle is 129.96
<h3>Right angle triangle</h3>
Right angle triangle are triangle that has one of its sides as 90 degrees. The sides can be found using Pythagoras theorem. Therefore,
c² = a² + b²
where
c = hypotenuse
a and b are the other legs.
Therefore,
19² - 15.2² = a²
a = 361 - 231.04
a = 129.96
