Answer:
x=24
Step-by-step explanation:
This is a right triangle so 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 + 10^2 = 26^2
x^2 +100 =676
Subtract 100 from each side
x^2 +100-100 = 676-100
x^2 = 576
Take the square root of each side
x = sqrt(576)
x =24
