We need at least 3 informations.
They are similar to that of the requirements for the two triangles to be congruent.
1. Angle - Side - Angle
2. Side - Angle - Side
3. Angle - Angle - Side (this one is not easy for drawing)
4. Side - Side - Side and
5. Right angle - Hypotenuse - Side
To solve, set an equation:
472=0.8x
Divide both sides by 0.8
472/0.8=0.8x/0.8
x=590
