Oil rig

The oil drilling rig is 23 meters in height and fixes the ropes, the ends of which are 10 meters away from the foot of the tower. How long are these ropes?

Correct answer:

x =  42.2 m

Step-by-step explanation:

$$\begin{gathered} h=41\text{m} \\ a=10\text{m} \\ {x}^2=h^2+a^2 \\ x=\sqrt{h^2+a^2}=\sqrt{41^2+10^2}=\sqrt{1781}=42.2\text{m} \end{gathered}$$
