Answer:

x=24

Explanation:

We can use the Pythagorean theorem to find x

a^2 + b^2 = c^2

where a and b are the legs and c is the hypotenuse

7^2 + x^2 = (x+1)^2

FOIL the right side (x+1) * (x+1) = x^2 +1x +1x+1 = x^2+2x+1

49+x^2 = (x^2 +2x+1)

Subtract x^2 from both sides

49+x^2-x^2 = (x^2 +2x+1) -x^2

49 = 2x +1

Subtract 1 from each side

49-1 = 2x+1-1

48 =2x

Divide by 2

48/2 = 2x/2

24 =x
