Answer:
x=8
Step-by-step explanation:
Remember that the variables a and b in the formula are the legs and c is the hypotenuse. So that means that 15 and x are the legs and 17 is the hypotenuse. Plug those numbers where they go in the formula like below:
15^2+x^2=17^2
Go ahead and square the 15 and 17 to simplify it a little.
225+x^2=289
Now, get the x by itself by subtracting 225 from each side
x^2=64
Take the square root of each side to remove the squared on x and solve.
x=8
1) x > -4 and x <span>< 2
2) x </span>> 4 and x <span><8</span>
Yes, 4/8 and 1/2 are equivalent, because 4/8 reduced to simplest form is 1/2.
