Question

Answer 1

i think it would be 8 inches even though i was pretty sure it was 10 but 8 seems to be the best answer 

Answer 2

Answer: d. 8 inches

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 :-

`\text{Area}=(1)/(2)* base* height\\\\\Rightarrow\ 40=(1)/(2)*10* h\\\\\Rightzarrow\ h=(40)/(5)=8\\\\\Rightarrow\ h=8\ inches`

Hence, the height of the triangle = 8 inches
