Step-by-step explanation:

the wall is straight so it makes 90° with ground so assume it as right angled triangle

by Pythagoras property :

13² - 5² = the top of stairscase reaches on wall

169 - 25 = the top of staircase reaches on wall

144 = the top of staircase reaches on wall

12² = the top of staircase reaches on wall
