PLEASE HELP ME ASAP

Answer 1

Use the formula a^2 + b^2 = c^2

Answer 2

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,
.

(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,
