The ratios of the sides are 12:12:x
Find x when the ratios are 1:1:x
and then multiply each side by 12
In the 2nd right triangle:
+x%5E2+=+1%5E2+%2B+1%5E2+
+x%5E2+=+2+
+x+=+sqrt%282%29+
Now multiply the sides by 12
+12%2A1+=+12+
+12%2A1+=+12+
+12%2Ax+=+12%2Asqrt%282%29+
+sqrt%282%29+=+1.414+
+12%2A1.414+=+16.97+
To the nearest foot, the 3rd side is 17 feet long
