Find X in Right Triangle: Area 18.5 and Height 10 Units

To find the missing side $X$ of the triangle:

• Step 1: Identify the given values: area $A = 18.5$ and height $h = 10$.
• Step 2: Use the area formula for a triangle: $A = \frac{1}{2} \times \text{base} \times \text{height}$.
• Step 3: Plug in the known values into the formula:
  $18.5 = \frac{1}{2} \times X \times 10$.
• Step 4: Simplify and solve for $X$:
  $18.5 = 5 \times X$
  Divide both sides by 5 to isolate $X$:
  $X = \frac{18.5}{5}$.
• Step 5: Calculate $X$:
  $X = 3.7$.

Therefore, the missing side $X$ is $3.7$.
