Unraveling the Mystery of Triangle Area Calculations

Chapter 1: Understanding Triangle Area
Can you tackle this geometry challenge?
In this scenario, the lengths of the triangle’s sides are unknown. However, their relationships are expressed in terms of x, and it is confirmed that this is a right triangle.
Are you able to calculate its area based on these clues?
I suggest you take a moment to pause, grab some paper and a pencil, and give it a shot. When you feel ready, continue for the answer!
Solution Approach
To start, we must remember that all side lengths need to be positive.
From the inequality, it follows that ( x + 6 ) is the hypotenuse of this triangle.
With this knowledge, we can utilize the Pythagorean Theorem to find the area.
Let’s expand the equation and rearrange the terms. This will lead us to a quadratic equation.
After solving the equation, we arrive at two potential solutions:
( x = 9 ) or ( x = -3 ).
Since a side length cannot be negative, we conclude that ( x ) must be 9.
Recall that the adjacent and opposite sides are represented as ( x ) and ( x + 3 ).
And that gives us the answer to our problem.
