Question

Can you help me, please? I have to find the restrictions on x .Thank you.

Answer 1

If angle A is greater than angle C, then side BC is greater than side AB.

`\begin{gathered} BC>AB \\ 8-x>4x+48 \end{gathered}`

Then, we solve for x

`\begin{gathered} -4x-x>48-8 \\ -5x>40 \\ x<-(40)/(5) \\ x<-8 \end{gathered}`

Hence, the restriction of x is that its value must be less than -8.
