Question

Find the value of x. 80 , 4x

Answer 1

From the given figure there are 2 parallel lines intersected by a transversal

Then they formed a pair of exterior alternate angles (80 degrees and 4x)

Since the exterior alternate angles are equal in measures, then

`4x=80^(\circ)`

Divide both sides by 4 to find x

`\begin{gathered} (4x)/(4)=(80)/(4) \\ x=20 \end{gathered}`

The value of x is 20
