Question

Solve for X A. x = 8/3B. x = 7 C. 13/3D. x = 2

Answer 1

The lenghts of AB equals that of AC. Since angle ABC= angle ACB= 44 degrees ( base angles of isosceles triangle )

$\begin{gathered} AC=AB \\ 3x+1=7 \\ 3x=7-1 \\ 3x=6 \\ x=\frac{6}{3} \\ \\ x=2 \end{gathered}$

The right choice is x=2
