Answer:

x = 23

Step-by-step explanation:

Given, \frac{x - 5}{2} = 9, solve for x.

Multiply both sides by 2

\frac{x - 5}{2} \times 2 = 9 \times 2

x - 5 = 18

Add x to both sides

x - 5 + 5 = 18 + 5

x = 23

Once you have the points they make a 3-4-5 triangle. The two legs are 3 and 4, so the hypotenuse has to be 5. Or you could use the pythagorean theorem a² + b² = c² 3² + 4² = c² 25 = c² c = 5
