Answer:
x=6
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
x^2 +8^2 = 10^2
x^2 +64 = 100
Subtract 64 from each side
x^2 +64-64 = 100 -64
x^2 = 36
Take the square root of each side
sqrt(x^2) = sqrt(36)
x =6
