18.56 feet
Catie creates a similar triangle with the ladder so we can create a proportion to solve for the height.

Convert all values to feet . 16in = 1.33 ft . 5ft 6 in = 5.5 ft
Insert values into proportions

Cross multiply to get
24.75=1.33x
divide both sides by 1.33
x=18.56ft
Use Pythagoras:
x² = (8.5)² + (5)²
x = √[(8.5)² + (5)²]
0.25 is it in decimal form
