Final answer:
The height of the triangle is 5 inches.
Step-by-step explanation:
To find the height of a triangle, we can rearrange the formula A = (bh)/2 to solve for h. In this case, the area is given as 50 in² and the base is 20 in. Plugging in these values into the formula, we get h = (2 * 50 in²) / 20 in = 5 in. Therefore, the height of the triangle is 5 inches.
