Question

Can you please help me with question #4 only with steps so i can follow along and understand?.

Answer 1

According to parallelogram:

`3y=12x`

And

`6x+12x=180`

So simplifying these:

`\begin{gathered} 18x=180 \\ x=10 \end{gathered}`

now put it in 1 equation:

`\begin{gathered} 3y=12(10) \\ y=(120)/(3) \\ y=40 \end{gathered}`

So the given angles are:

`\begin{gathered} 3y=3(40)=120 \\ 6x=6(10)=60 \\ 12x=12(10)=120 \end{gathered}`
