Question

In the diagram above <3=40* Find the measure of <2. <2={?}*

Answer 1

Given:

`\angle3=40\degree`

Required:

`\text{ We need to find }\angle2.`

Step-by-step explanation:

`We\text{ know that }\angle3\text{ and }\angle2\text{ are alternate interior angles.}`

Alternate interior angles are equal in the parallel line.

`\angle2=\angle3`

`Substitute\text{ }\angle3=40\degree\text{ in the equation.}`

`\angle2=40\degree`

Final answer:

`\angle2=40\degree`
