Since angles ∠1 and ∠2 are complementary, their measures add up to 90 degrees. Given that \( m∠2 = 26° \), you can write the equation for \( m∠1 \) as follows:
\[ m∠1 + m∠2 = 90° \]
Substituting the measure of \( m∠2 \):
\[ m∠1 + 26° = 90° \]
So the equation to solve for \( m∠1 \) is:
\[ m∠1 + 26° = 90° \]
