Answer: Part A. a student must find the missing length by using the Pythagorean theorem.

The answer should come out to be x=2√26 or x=−2√26 (Decimal: 10.19803902…, -10.19803902…) or (Rounded to the nearest tenth: 10.20, -10.20)

Explanation:

Let's make x the missing length. The Pythagorean theorem says the way to set up this equation is the leg^2 + leg^2 = hypotnues^2.

Set up the problem and solve, I'll show you how to do it: x²+11²2=15²

Step 1: Simplify both sides of the equation.

x² + 121=225

Step 2: Subtract 121 from both sides.

x² + 121−121=225−121

x² = 104

Step 3: Take square root.

x = ± √104

The answer should come out to be x = 2√26 or x = −2√26 (Decimal: 10.19803902…, -10.19803902…) or (Rounded to the nearest tenth: 10.20, -10.20)
