Question

write an equation to show how ( mangle 1 ) and ( mangle 2 ) are related.

Explanation:

Step1: Identify angle relationship

∠1 and ∠2 form a linear pair, so their measures sum to 180°.

Step2: Write the equation

Using the angle measures \( m\angle1 \) and \( m\angle2 \), the equation is \( m\angle1 + m\angle2 = 180^\circ \).

Answer:

\( m\angle1 + m\angle2 = 180^\circ \)
