6^2 + h^2 = 10^2
36 + h^2 = 100
h^2 = 64
h = 8
or you can see that this is a 3 - 4 - 5 right triangle
36 + h^2 = 100

Since this forms a right angle triangle, we can use the Pythagorean Theorem.
a^2 + b^2 = c^2
a^2 + 6^2 = 10^2
a^2 + 36 = 100
a^2 = 64
a = 8
a^2 + b^2 = c^2
a^2 + 6^2 = 10^2
a^2 + 36 = 100
a^2 = 64
a = 8
