Question

Please help I don't understand how to find the other side

Answer 1

Answer:

x = 6 units

Explanations:

The triangle shown is a right angled triangle.

To make it obvious, it can be redrawn as shown below

The area of a right-angled triangle is given by the formula:

`\begin{gathered} \text{Area = }(1)/(2)* base* height \\ \text{Base = 6} \\ \text{Height = x} \\ \text{Area = 18 units}^2 \end{gathered}`

Substituting the necessary parameters into the formula

`\begin{gathered} 18\text{ = }(1)/(2)*6* x \\ 18\text{ = 3x} \\ x\text{ = }(18)/(3) \\ x\text{ = 6 units} \end{gathered}`
