# Two perpendicular sides of a triangle are 5.53 m and 7.41 m long, respectively. How do you find the length of the third side of the triangle and the smallest angle?

I don't know how to solve the smallest angle as I can't do trigonometry yet, but the longest side is $12.94$.
${5.53}^{2} + {7.41}^{2} = {\left(5.53 + 7.41\right)}^{2} = {12.94}^{2}$
The third side (hypotenuse) is $12.94$.
