I am not sure of the question so this is what I got based off of just the image.
Based on the information provided, we can calculate the length of the hypotenuse of each triangle using the Pythagorean theorem:
h = sart(3^2 + 4^2)
h = sart (9 + 16)
h = sart (25)
h = 5
So the length of the hypotenuse of each triangle is 5cm.
To find the length of the slope, we can use the Pythagorean theorem again:
L= sart(5^2 + 11^2)
L= sqrt(25 + 121)
L= sart(146)
L~ 12.083
So the length of the slope is approximately 12.083cm.
