There is no solution unless you either know the interior angle, or you know it is a right triangle.
The Pythagorean Theorem can be used.
.
Assuming the 13 is the hypotenuse,
.
13%5E2+=+x%5E2+%2B+10%5E2
169+=+x%5E2+%2B+100
69+=+x%5E2
x%5E2+=+69
x+=+sqrt%2869%29
x+=+8.30662386
.
Assuming the hypotenuse is unknown.
.
c%5E2+=+10%5E2+%2B+13%5E2
c%5E2+=+100+%2B+169
c%5E2+=+269
c+=+sqrt%28269%29
c+=+16.4012195
.
Done.
