Answer:

x=8

Step-by-step explanation:

To solve this, we must use the Pythagorean theorem.

a=15, b=x, and c=17

[tex](15)^2 +b^2=(17)^2\\\\b=\sqrt{17^2-15^2} \\\\b=\sqrt{289-225} \\\\b=\sqrt{64} \\\\b=8[/tex]

a^2+b^2=c^2

In this case, 15=a and 17=c and if you substitute the variables as the numbers, you would get the equation 15^2+b^2=17^2. If you simplify that you would get 225+b^2=289. You subtract 225 from both sides and you get left with b^2=64. The square root of 64 is 8 so I’m this problem x is 8.
