Question

Find the value of x using the angle relationships below

Answer 1

Answer:'

x=20

Explanation:

In the diagram, angles 3x and (2x+20) degrees are alternate exterior angles,

This thus means that they are congruent.

Thus:

`\begin{gathered} 3x=2x+20 \\ \text{ Subtract 2x from both sides:} \\ 3x-2x=2x-2x+20 \\ x=20 \end{gathered}`

The value of x is 20.
