Answer:
$79.63
Step-by-step explanation:
You can figure this by estimating. 16% is a little less than 20%, which is 1/5. $497.69 is almost $500. So, 1/5 of that is almost $100, and a little less than that is about $80. The closest answer choice is $79.63.

The Pythagorean Theorem states that a triangle's hypotenuse is equal to the square's of the other two sides of the triangle.
a² + b² = c<span>²
a = side of triangle
b = other side of triangle
c = hypotenuse (squared)
Find the square root to find the accurate length of the hypotenuse.</span>
