Answer:

The length of the hypotenuse is 10.9ft

Explanation:

To calculate one side of a right triangle from the other 2 sides we have to use Pythagoras

h = hypotenuse

a = leg 1 = 6.8ft

b = leg 2 = 8.5ft

h² = a² + b²

we replace the known values

h² = (6.8ft)² + (8.5ft)²

h² = 46.24ft² + 72.25ft²

h² = 118.49ft²

h = √(118.49ft²)

h = 10.8853 ft

Round to the nearest tenth

h = 10.8853 ft = 10.9ft

The length of the hypotenuse is 10.9ft
