Using the Pythagorean theorem ~ a² + b² = c² ~, if this is true then the triangle is a right triangle.
a) 5² + 10² = 15²
25 + 100 = 225 *FALSE*
b) 13² + 35² = 37²
169 + 1225 = 1369 *FALSE*
c) 9² + 40² = 41²
81 + 1600 = 1681 *TRUE*
d) 6² + 9² = 10²
36 + 81 = 100 *FALSE*
The answer is C) 9, 40, 41.

Answer:
288 and 289 are the two pages.
Step-by-step explanation:
We will start with Chris's age, since Sue is older than him and Jim is older than Sue. Chris is the youngest. We will say Chris's age is x. If Sue is 2 years older than Chris, Sue is x + 2. Jim is 4 years older than Sue, so Jim is 4 + x + 2, or x + 6. The total of their ages is 68, so x + x + 2 + x + 6 = 68. Simplifying we have 3x + 8 = 68. 3x = 60, so x = 20. Chris is 20, Sue is 22, and Jim is 26. Those numbers do in fact total 68.
