a^2+b^2=c^2

a=x

b=11

c=12

a squared=c squared-b squared

12 squared is 144

11 squared is 121

144-121=23

The square root of 23, rounded to the nearest hundredth, is 4.80

Answer:

4.8 ft

Explanation:

The given diagram suggests the height is the unknown leg of a right triangle with hypotenuse 12 ft and one leg 11 ft. Then the Pythagorean theorem tells you the length of the other leg is ...

? = √((12 ft)^2 -(11 ft)^2) = √(23 ft^2) ≈ 4.8 ft
