Answer:
x = 15 units
Step-by-step explanation:
Here, base of triangle = x units & height = 19 units
[tex]Area( \triangle) = \frac{1}{2} \times base \times height \\ \\ 75 = \frac{1}{2} \times x \times 10 \\ \\ 75 = x \times 5 \\ \\ x = \frac{75}{5} \\ \\ \huge \purple{ \boxed{ x = 15 \: units}}[/tex]
