We see that this right triangle has a 30°-angle, meaning the remaining angle must be 60° (sum of angles must be 180°). This means the triangle is what we call a special right triangle, specifically, a 30°-60°-90° triangle.
The sides of such a triangle are in a ratio where the shortest leg (across from the 30°-angle) is x, the hypotenuse is 2x, and the longest leg is x√3.
Here, we are given the shortest leg, 53.57 cm. To get the hypotenuse, we double this length to get 107.14 cm.
