Answer: d. 8 inches

Step-by-step explanation:

Given: The area of triangle = 40 sq. inches

The base of the triangle = 10 inches

Let h be the height of the triangle.

The area of a triangle is given by :-

[tex]\text{Area}=\frac{1}{2}\times base\times height\\\\\Rightarrow\ 40=\frac{1}{2}\times10\times h\\\\\Rightzarrow\ h=\frac{40}{5}=8\\\\\Rightarrow\ h=8\ inches[/tex]

Hence, the height of the triangle = 8 inches
