Answer 2

Answer: D. x= 24 in

Explanation:

Given:The area of the triangle =
`84\ in^2`

In the given picture, it can be seen that the height of the triangle = 7 inches

Also, the base of the triangle = x

We know that the area of the triangle is given by :-

`\text{Area}=(1)/(2)*base*height\\\\\Rightarrow\ 84=(1)/(2)*x*7\\\\\Rightarrow\ x=(84*2)/(7)\\\\\Rightarrow\ x=24`

Hence, the value of x=24 in.
