Question

Find the value of x that will make A||B5x + 20A-В.3x + 60x= [?]Enter

Answer 1

The value of x is 20

Explanation:

By properties of the angles we know that these angles are equal, since they are alternative external angles. Thanks to that we can do the following equality to calculate the value of x:

`5x+20=3x+60`

Solving for x:

`\begin{gathered} 5x-3x=60-20 \\ 2x=40 \\ x=(40)/(2) \\ x=20 \end{gathered}`
