Question

Help how to answer 4 how to find x and y

Answer 1

Since:

We can use CPCTC ( Corresponding parts of congruent triangles are congruent) so:

`\begin{gathered} m\angle A=m\angle D \\ 60=5y \\ so\colon \\ y=(60)/(5) \\ y=12 \end{gathered}`
`\begin{gathered} 6x-4=3x+26 \\ 6x-3x=26+4 \\ 3x=30 \\ x=(30)/(3) \\ x=10 \end{gathered}`
