ANSWER
x = 8
Step-by-step explanation
Here we have a right triangle. The lengths of two sides are given and we have to find the length of the third side. To do so, we will use the Pythagorean Theorem,
![c^2=a^2+b^2](https://img.qammunity.org/2023/formulas/mathematics/high-school/udh1dsx7kwgfauditnn86pp2qhoycm1tvv.png)
Where a and b are the legs, and c is the hypotenuse.
The hypotenuse of a right triangle is always the longest side, which is the side opposite to the right angle. In this case, the hypotenuse is 10 units long, one of the legs is 6 units long and we have to find the length of the other leg, x,
![10^2=x^2+6^2](https://img.qammunity.org/2023/formulas/mathematics/college/15mfn6spmhd54ab54sak03e6lijlinilov.png)
Solving for x,
![x=√(10^2-6^2)=√(100-36)=√(64)=8](https://img.qammunity.org/2023/formulas/mathematics/college/lfkb3ul7wj1uoz2wb0rxryjy6hrfi78naq.png)
Hence, the value of x is 8.
