Hello!
As you can see where are given ? side length. We will use the Pythagorean Theorem (a²+b²=c²) to find all of the side lengths of the triangle. When we find the hypotenuse (c, the side that contains the ?) we will subtract 1128 from it to find ?.
1457²+1692²=c²
2,122,849+2,862,864=4,985,713
√4,985,713≈2232.87
2232.87-1128=1,104.87
Therefore, the missing side length is about 1,104.87.
I hope this helps!
