Answer:
24 mm
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x be the other leg, then
x² + 10² = 26²
x² + 100 = 676 ( subtract 100 from both sides )
x² = 576 ( take the square root of both sides )
x = [tex]\sqrt{576}[/tex] = 24
The length of the other leg is 24 mm
