A=16, c=14 find the length of b if necessary round to the nearest tenth

None

Step-by-step explanation:

Assuming you mean sides of a right triangle, we can use the Pythagorean theorem (A^2 + B^2 = C^2)

We have A and B, so we can plug those into the equation.

(16) ^2 + B^2 = (14) ^2

(16) ^2 is 256 and (14) ^2 is 196. Plug those in.

256 + B^2 = 196

Get rid of the 256 by subtracting.

B^2 = 196 - 256

B^2 = - 60

√B^2 = √-60

You can't take the square root of a negative number, so the solution is not possible. We can confirm because C cannot be bigger than A or B.
