Answer:

Look below

Explanation:

(a)

The Pythagorean Theorem is a^2+b^2=c^2. In this case. a=10, b=y, and c=2+y.

So,
(2+y)^(2)=10^(2)+y^(2).

(b)

Using the equation (2+y)^2=10^2+y^2, solve for y.

  • (2+y)^2=10^2+y^2
  • Square it, 4+4y+y^2=100+y^2
  • Subtract y^2, 4+4y=100
  • Subtract 4, 4y=96
  • Divide by 4,
    y=24.
