Answer: 12.32 is the answer.


Step-by-step explanation: Using the pythagorean thereom we can solve this by using the formula A^2+B^2=C^2.

We substitute in the values,


17^2+B^2=21^2.


Now we simplify.


289+B^2=441


We subtract the 289 from both sides,


B^2=152


Now we use square root to find the answer.


12.32 is the answer.


Hope this helps!

h^2 = b^2+p^2

21^2 = 17^2+x^2

441 = 289 + x^2

441-289 = x^2

122 = x^2

square root of 122 is x.

therefore, x= 11.04536102.
