Answer:
b=8
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2+b^2 =c^2 where a and b are the legs and c is the hypotenuse
6^2 + b^2 = 10^2
36+b^2 = 100
Subtract 36 from each side
b^2 = 100-36
b^2 = 64
Take the square root of each side
sqrt(b^2) = sqrt(64)
b = 8
