What is the value of x enter your answer in the box x=

x = (3√34 + 1)/5 units

Step-by-step explanation:

Let's solve for x, using the Pythagorean theorem, this way:

BC is the Hypotenuse of the triangle ABC

BC² = 15² + 9²

BC² = 225 + 81

BC² = 306

BC = √9 * 34

BC = 3 √34

Now, we can substitute and solve for x, this way:

BC = 3x + 2x - 1

3 √34 = 3x + 2x - 1

3√ 34 + 1 = 5x

x = (3√34 + 1)/5 units
